Is Lead Magnetic?

Lead is an intriguing material known for its unique properties. One question that often arises is whether lead is magnetic. After all, lead is a heavy metal, right? In this post, we will discuss the science behind magnetism, explore the magnetic properties of lead, and uncover the truth behind this common misconception.

Before we discuss the specifics of lead’s magnetic properties, it is essential to understand the fundamentals of magnetism. In our world, electrons are just one of the many particles that make up everything, including magnets. A magnetic field is created when electrons align in the same direction, harnessing their negative charge. In most cases, a magnet does not need to touch an object to interact. We see examples of magnetism in our everyday lives, some of the most prevalent ones being fridge magnets, computer magnets, and MRI machines.

Contrary to popular belief, lead is not inherently magnetic since it is a diamagnetic material. Being diamagnetic means it has paired electrons that provide no magnetic moment. Just like gold, lead is also considered a metal, but because of its many properties that include being diamagnetic, it does not hold those magnetic capabilities. Other diamagnetic elements that are also often mistaken for being magnetic include bismuth, silver, and copper. Understanding the distinctions between diamagnetic and magnetic materials is crucial, especially in fields like electromagnetism.

Uses for Lead

Although lead may not be helpful when demonstrating magnetic capabilities, it can be used in a wide variety of products, such as battery manufacturing and radiation shielding. Lead is still widely used, but its toxicity has prompted bans in specific applications, such as new plumbing. Many regulations and initiatives are in place to reduce lead exposure and promote safer alternatives. These alternatives can include the development of nontoxic substitutes for lead-based products and the implementation of rigorous standards for lead content in consumer goods.

How are magnets made?

Magnets are amazing objects that are used in countless applications. Their ability to interact with metals and other magnets in a truly unique way has continually fascinated scientists. Magnets have been around for almost as long as the Earth, but earlier magnets were generally weak and extremely rare to most people. Today, extremely strong neodymium magnets are made every day and are available to almost everyone. This ability to manufacture such powerful magnets has led to countless breakthroughs, from speakers and hard drives to powerful electric motors and MRI machines. Let’s take a look at the process of making strong neodymium magnets.  


Mining and Milling 


Neodymium magnets are made from a combination of metals that must be mined from the Earth. Just like gold, these rare-earth metals are collected from large mines and transported to a mill to be crushed down into more manageable sizes. Neodymium magnets, the strongest commercially available magnets, are made from a combination of iron and neodymium. Both of these materials are ferromagnetic, meaning that they have the ability to hold a magnetic field. This means that these metals are basically already magnets, but the alignment of the material does not produce a strong magnetic field in one direction. China, boasting the most significant reserves and the highest production capacity, dominates the rare-earth market, contributing over sixty percent of the world’s supply. They also are the largest producers of finished magnets. The largest mine in the world is the Bayan Obe mine in North China. This single mine holds over 40 million tons of rare-earth material. 


Separation and Sintering 


Once the materials have been mined and milled, they are sent to a separation facility where the different metals are separated out, collected, and sent to the manufacturing factories. Once the metals reach the manufacturing factories, they are broken down into a very fine powder. This process ensures that as much of the material can be aligned toward the desired direction in later processes. The more material aligned, the stronger the magnet. After this, the fine powder is pressed into the desired shape and placed into a sintering furnace. This furnace helps to ensure that the material is joined permanently together and will not easily fall apart by “sintering” the material together. Final Preparations and Magnetization At this point in the process, the material for the magnet is ready for the final fine-tuning processes before magnetization. The blocks of material are machined down to the precise dimensions required and plated with a protective coating to prevent the rusting of the magnet. There are many different plating options for a variety of applications. If you are interested in learning more about the various available plating options, you can find a helpful guide here on our website. After plating, the block of magnetic material is given one final inspection to ensure that the coating and the dimensions of the magnet are correct. Once everything is checked, the material is ready to become a magnet. It is placed into a machine that delivers a powerful magnetic field through the material, forcing the alignment of the magnetic material. The now-aligned magnet will produce a strong magnetic field. The magnet is now a fully functional and very powerful permanent magnet ready to be used in a countless number of applications. 




These amazing magnets represent a triumph of human ingenuity and technological advancement. From the fine powder stage to the precision machining and protective plating, every step is essential in crafting magnets capable of powering speakers, propelling electric vehicles, and facilitating medical diagnoses. What will you use these powerful magnets for?

Choosing Between Glass boards and Whiteboards: Which is Right for Your Workspace?


If you ever spend time looking for a new writing surface, you will most likely come across two popular choices: glass boards and whiteboards. Both use erasable markers and can be found in offices, classrooms, and hospitals everywhere. While both are excellent options, it is a good idea to look at the differences between the two choices to make the best choice for your unique space. 




Traditional whiteboards hold their ground with a familiar usability that many find comforting. They boast versatility in terms of size and installation options which makes them a great choice for a wide range of environments and preferences. A whiteboard can cover an entire wall or can be a small, hand-held board for notetaking or a quick game of hangman in the car. The whiteboard is also very light allowing nearly anyone to move even a larger one from room to room. As with both of our options, the whiteboard’s strength lies in its ability to keep a space clean and organized. They also allow for a spectrum of color possibilities beyond the simple white of the chalkboard, making it easier to organize information and helping prevent whoever is using the board from being covered in clouds of white powder. One of the few downfalls of the whiteboard is that it must be regularly cleaned to avoid leaving smudges and colored “fog” on the board. The best way to prevent this from happening is to clean the board after every use and to avoid leaving writings or drawings on the board for too long.  

Glass Boards 

 The glass board is like the whiteboard in many ways with the main difference being (you guessed it) a glass writing surface. Glass boards exude a sleek and modern aesthetic, elevating the ambiance of any workspace. Glass boards are favored in contemporary office environments for their smooth appearance and durability, adding a touch of sophistication and making a stylish statement. The boards can come in many different colors and different transparencies allowing you to choose a board that fits the design of your space. Durability is another key advantage of glass boards. Unlike traditional whiteboards, which can become scratched or stained over time, glass boards are highly resistant to wear and tear. The non-porous surface of the glass is easy to clean and maintain, ensuring a pristine writing surface that retains its clarity and brilliance even with regular use. One downfall of the glass board is that it can be extremely heavy and may sometimes even require special installation. 

 Additional Factors to Consider  


Magnetic Capabilities  


Considering magnetic capabilities is essential when selecting the appropriate board. While traditional glass boards may offer magnetic features as an add-on compared to traditional whiteboards, tempered glass inherently lacks magnetic properties. However, you can opt for glass boards with embedded magnets for a convenient display of documents and lightweight materials. In contrast, whiteboards are naturally magnetic, thanks to the metal backing beneath the smooth surface. Whether the board you are considering is magnetic or not is something to take note of.  

Cost Considerations 

 If you are looking for a more budget-friendly option, whiteboards tend to offer a more friendly option compared to glass boards. However, while glass boards may require a higher initial investment, their durability and longevity can justify the upfront cost in the long run.

Neodymium Magnet Grades: Unveiling the Spectrum of Strength



Neodymium Magnets


While there are many standards for naming permanent magnets, using “grades” or grade names is the primary classification for most Neodymium magnets. Understanding these grades is important to finding the right magnet for your application, but it can be nearly impossible without first understanding how to interpret the different grade names correctly.

Reading Magnet Grades

Magnetic Grade Chart

The various grades for Neodymium magnets are each denoted by letters and a number. This combination of letters and numbers signifies the strength of a magnet and its temperature resistance. The strength of the magnet is indicated by the number, which tells the BHmax of the magnet. BHmax is simply a representation of magnetic flux or magnetic strength. For example, an N35 magnet will have a BHmax or strength of around 35. The image to the side shows some of the basic grades of Neodymium along with their temperature maximums and BHmax. As the number in the grade name increases, so does the strength of the magnet. How much increase? Going from an N40 magnet to an N52 magnet will generally result in around a 30% increase in strength.

The letters in the name denote the material being used in the magnet. This material determines the temperature resistance of the magnet or the “Tmax”. A magnet’s Tmax is simply the temperature level at which the magnet can become compromised and start losing strength. There are options for magnetic materials with temperature resistance as high as 446°F.

There are many grades of Neodymium for all types of applications. The most commonly used grades include N35, N40, and N52. For most applications that do not require the magnets to be able to resist high temperatures, these grades will work perfectly. If you are interested in seeing a full chart of all the available grades of Neodymium, you can find one here on our website.

Additional Factors to Consider


When looking for a magnet for a specific application, price can definitely be a determining factor. Generally, the higher the strength of the magnet, the higher the price. How much higher? The price difference between an N40 grade magnet and an N52 grade magnet is generally around 15%. The same is true for temperature resistance. The higher the resistance temperature, the higher the cost. The cost of increasing the temperature resistance of a magnet is generally small at lower temperatures but increases dramatically once extreme temperatures are needed.

Material Brittleness

Another factor to consider when looking at magnet grades is brittleness. As the strength or the temperature resistance of a magnet increases, so does its susceptibility to cracking and chipping. This is because of the different materials being used as well as the tendency of stronger magnets to attract themselves internally. While this increase in weakness is not extreme, it is something to be aware of when choosing a magnet for your specific project.


Understanding magnet grades is a useful skill to possess. Hopefully, this little article has helped you not only gain the necessary knowledge to understand magnet grades but also the confidence needed to make informed decisions about what magnet is best for your project. If you have any questions about grades or what would be suitable for your application, please feel free to contact us at 1-512-678-2940 or visit our website at

Magnetic Levitation: The Future of Transportation?


In the realm of transportation, one concept stands out as both complex and promising: magnetic levitation, often referred to as maglev technology. This revolutionary mode of transportation has captured the imagination of engineers, innovators, and commuters alike, offering the potential for ultra-fast, frictionless travel. The foundational principles of magnetic levitation were understood in the early 20th century, with significant advancements occurring throughout the mid to late 20th century. Practical applications of maglev technology for transportation emerged in the latter part of the 20th century, with the first operational maglev train, the SCMaglev, being developed and tested in Japan in the 1970s and 1980s. So, while the principles behind maglev technology have been understood for a long time, its practical application for transportation purposes has only recently begun to develop.  


Understanding Maglev Technology 

 At its core, magnetic levitation relies on the fundamental principles of electromagnetism to suspend and propel vehicles along a specially designed guideway without the need for traditional wheels, axles, or rails. This allows for achieving extreme speeds without creating excessive friction. The two primary types of maglev technology are electromagnetic (EMS) and electrodynamic (EDS) systems. EMS systems utilize electromagnets to create a magnetic field that repels the train from the guideway, allowing it to levitate. This is achieved by passing an electric current through coils in the guideway, which generates a magnetic field that interacts with other electromagnets or permanent magnets on the underside of the train. EMS systems are known for their stability and ability to adjust to changes in load and speed. On the other hand, EDS maglev systems utilize the principles of electromagnetic induction. In an EDS system, the magnets on the train induce currents in the guideway coils as they pass over them. These induced currents create a magnetic field that repels the magnets on the train, causing it to levitate. EDS systems are typically known for their high-speed capabilities and efficiency, as they don’t require power to be constantly supplied to the guideway coils. This makes EDS systems a compelling choice for high-speed trains.  


Real-life Examples 

While still in its infancy compared to traditional modes of transportation, maglev technology has demonstrated significant potential through various applications around the world. One of the most prominent examples is the Shanghai Maglev Train in China, which is the world’s fastest commercial maglev train, achieving speeds of up to 267 mph! This remarkable achievement underscores the immense capabilities of maglev technology for high-speed rail systems. Beyond Shanghai, maglev trains have been proposed and developed in several countries to address urban congestion, enhance intercity connectivity, and reduce travel times. Projects such as the proposed Chūō Shinkansen in Japan and the experimental Transrapid system in Germany serve as testaments to ongoing efforts to implement maglev technology on a larger scale. 



Challenges and Future Prospects  

Despite its promise, maglev technology faces several challenges that have hindered its widespread adoption. Chief among these challenges are cost, infrastructure requirements, regulatory hurdles, and public perception. The significant investment needed to develop maglev infrastructure, including specialized guideways and stations, has been a barrier to entry for many regions. Concerns regarding safety, reliability, and compatibility with existing transportation systems have contributed to skepticism among policymakers and the public alike, preventing many proposed projects from ever starting. However, ongoing advancements in materials science, magnet technology, and infrastructure development are steadily addressing these challenges, paving the way for the broader acceptance and deployment of maglev systems.

A Brief History of Magnets

Early History China

The Great Wall of China

The history of magnets stretches back thousands of years, with evidence of their use dating back to ancient civilizations. One of the earliest known uses of magnets was in China around 200 BC. The Chinese were among the first civilizations to harness the magnetic properties of naturally occurring lodestone for practical purposes. Historical records indicate that by the 2nd century BCE, Chinese scholars had developed sophisticated compasses, known as “south-pointing chariots,” using lodestone suspended in water or on a floating platform to align with the Earth’s magnetic field. This innovation revolutionized maritime navigation, allowing sailors to venture into uncharted waters with greater confidence and accuracy. In addition to their practical applications, magnets held symbolic significance in ancient Chinese culture. Because the scientific knowledge of magnets was extremely limited at that time, magnets were considered to be mystical objects that defied the normal rules of nature. They were associated with harmony, balance, and the five elements (wood, fire, earth, metal, and water) in traditional Chinese cosmology.


Ancient Greeks also made significant contributions to the understanding and use of magnets. In ancient Greece, the study of magnets was primarily driven by philosophical inquiry and scientific curiosity. Around 600 BCE, the philosopher Thales of Miletus observed that lodestone had the property of attracting iron, thus becoming one of the earliest documented instances of magnetic attraction and laying the foundation for the study of magnets and their attraction to different metals. The Greeks further explored the properties of magnets, leading to the discovery of vast stores of loadstone in the region of Magnesia, Asia Minor. This region is where we get the name “magnet” from. After the ancient discoveries made by civilizations like Greece and China, the study of magnetism continued to evolve across various regions and cultures, leading to significant advancements in understanding and utilizing magnets.

Renaissance Period

The Renaissance period (14th to 17th centuries) saw a resurgence of interest in classical learning and scientific inquiry in Europe. During this time, notable scholars such as William Gilbert, Tycho Brahe, and Johannes Kepler made significant contributions to the study of magnetism. William Gilbert, a renowned English physician, is often considered to be the “father of magnetism” for his groundbreaking work “De Magnete” in 1600. In his pivotal work, Gilbert conducted extensive experiments and observations on magnets, proposing that the Earth itself was a giant magnet and introducing the concept of magnetic poles. His work laid the groundwork for the understanding of magnetism to continue developing during the early modern period, with scientists like Robert Boyle, Edmond Halley, and Isaac Newton making further contributions that shaped the understanding and research of magnets moving forward. While discoveries about how magnets work and behave continued to be abundant, the inability to readily make strong magnets limited the practical applications of magnets until later in the modern era.

The Modern Era

Michael Faraday
The 19th and 20th centuries witnessed rapid progress in the study and application of magnetism, driven by advancements in science and technology. The development of stronger microscopes allowed scientists to see further into magnets than ever before and make critical findings about how magnets work. Perhaps the most notable magnet scientist of his period, Michael Faraday conducted experiments with electricity and magnetism that laid the foundation for the fascinating field of electromagnetism, leading to the development of electric motors, generators, and transformers. Since then, the discoveries around magnets have allowed scientists to create strong man-made magnets that are used in MRI machines, electric motors for cars, speakers, and headphones, and even the International Space Station. The widespread use of magnets in our daily lives is a testament to the transformative impact of past discoveries and innovations in magnetism. As technology evolves and scientific understanding deepens, magnets are expected to continue to play a critical role in applications of all kinds.

Do Magnets Work in Space?

The fascination of space sparks the imagination, leading to fascinating questions about everyday objects. Will a feather fall just as fast as a hammer on the moon? If you fire a bullet out into space, will it simply go on forever until it collides with some distant planet or star? If you are flying around the Earth on the International Space Station, will magnets still behave in the same fashion that they behave here on Earth?

Space is an amazing place that humans are just beginning to scratch the surface of. There have been countless exciting experiments on things such as water and fire, seemingly simple things here on Earth that behave very curiously when they are in outer space. Many experiments have also been done on magnets, allowing us to debunk many myths and confirm many cool facts about magnets in space.

Do magnets lose their strength in space?

Imagine you are out in space with two magnets in each hand. Would they still attract and repel each other, or would they simply come together like simple pieces of metal?
As you brought the magnets closer to each other, you would find that they would snap together just like on Earth. No problems at all. Magnets work perfectly in space. Why is that?
Magnets create their own magnetic field that does not need anything to travel through. This means that a magnet would perform the same in a vacuum as it would in regular air. This also means that outer space does not pose any issue to a magnet’s performance. The only thing that could cause a magnet to fail in space would be extreme heat, as magnets often have a temperature maximum of around 176 degrees Fahrenheit. Go beyond this temperature, and the magnets would begin to lose their strength.

Are magnets used in space?

So, if magnets work in space, are they used by astronauts and space equipment? Yes! Magnets play a very important role in spacecraft. In fact, many magnetic tools were used to help get the astronauts of the Apollo 11 mission to the moon and also to navigate the International Space Station.

Attitude Control:

Magnets are integral to spacecraft for attitude control. Through the use of magnetic torques, they can adjust their orientation without relying on fuel-consuming thrusters, ensuring stable positioning in space.

Magnetic Shielding:

In space, where radiation from the sun and other celestial bodies is prevalent, magnets play a crucial role in shielding sensitive instruments. This protection ensures the functionality and integrity of onboard equipment by redirecting or deflecting harmful charged particles, just like a real shield.


Magnets are essential components in the instrumentation of spacecraft. They contribute to the proper functioning of magnetometers, which are devices that measure the strength and direction of magnetic fields. This information is crucial for scientific experiments and exploration missions in space.


Magnets indeed work in space and maintain their attractive and repulsive properties. Their ability to create a magnetic field without the need for a medium allows them to function seamlessly in the vacuum of outer space. Magnets are not only operational but also play critical roles in space exploration. As humanity delves further into the mysteries of space, magnets prove to be indispensable tools. What other everyday objects do you think could defy our expectations when exposed to the unique conditions beyond our planet?

Do Magnets Stick To Aluminum?

Aluminum Raw Element

It is metal, right? 

If you have ever played with magnets as a kid, you were probably perplexed and surprised to find that your magnets just don’t seem to like certain types of metal. Why is that? Are some metals different than others? Let’s take a quick look at why magnets are not drawn to certain metals and how aluminum fits into the picture.


Why does it stick?

At the heart of magnetic attraction lies the alignment of electrons within certain materials, particularly metals. Metals like iron and steel, known as ferromagnetic materials, have electron configurations that readily respond to magnetic forces, allowing magnets to stick to them effortlessly. This is because an unequal distribution of electrons in these materials results in “mini magnets” called domains being formed within the atomic structure. When a magnet gets close to the material, these domains align with the magnet’s field, causing the material itself to turn into a weak magnet momentarily. This is why a nail can pick up paper clips shortly after being near a strong magnet.


Do magnets like aluminum? 

Contrary to ferromagnetic metals, aluminum belongs to the category of non-magnetic materials. The absence of magnetic attraction in aluminum can be traced back to its electron structure. Although aluminum does contain electrons, the more equal arrangement of these electrons doesn’t allow for a substantial magnetic field. As a result, magnets are not attracted to aluminum.


What about Eddy Currents?

While aluminum itself is non-magnetic, it is an amazing conductor of electricity. Because of this, an interesting phenomenon comes into play when a strong magnet field is moved past it. As a strong magnetic field moves past the material, the movement of the electrons in the material generates a magnetic field. This magnetic field generated by the material is opposite to the magnetic field of the magnet passing by. Because of this, a resistance between the magnet and the material is formed. This remarkable reaction is called an Eddy current. Eddy currents are extremely useful because of their resistance properties and are often used for frictionless brakes that can be found on almost any rollercoaster.



The mystery of why a magnet won’t stick to certain metals unravels through the intricate interplay of electrons and magnetic forces. The atomic world is truly one that keeps surprising scientists with amazing new applications all the time. While aluminum does not stick to magnets, the presence of eddy currents adds an extra layer of complexity, showcasing the versatility of aluminum in applications where its non-magnetic nature is an advantage.
