Scrap metal is one of the most recycled commodities, and magnets are an important part of metal recycling.Recycling metal has been a common practice for centuries. The ancient Romans recycled captured bronze statues into armor and weapons. The Vikings smelted and repurposed used or broken weapons. Metal scrapyards become common in the 1920s. Airplane and automotive parts during the 1940s relied heavily on recycled metal.Magnetic Separation of MetalsRecycling begins with separating differe …

Neodymium magnets are strong permanent magnets made from an alloy of rare-earth elements. They are a type of rare-earth magnet, and they are the most widely used rare-earth magnet. They’re also the strongest kind of permanent magnet commercially available. Rare Earth Magnets Rare earth metals are relatively abundant in the Earth’s crust, but it’s hard to find them in significant concentrations. Though plentiful, they are dispersed very evenly across the Earth. Unlike coal or iron, w …

Magnets Bring Family Together Your home is your sanctuary – a refuge to reconnect with family and friends. At the end of the day, no other place has a stronger attractive power or charm. Here, loved ones come together. Whether gathering with others for a meal or activity, or relaxing alone in a shared space, your home is where it happens.  The allure of a permanent haven, free from the distractions of the world outside, has a deep-rooted resonance.  Your home is deeply integr …

Wind Power: Clean Energy with Magnets Wind energy has developed into one of the most viable clean sources of renewable energy in the world. It reduces air pollution, including sulfur dioxide, nitrogen dioxide, nitric oxide and particulate matter often emitted from other energy production methods. In the United States, wind energy is one of the fastest growing energy sources in the utility sector. According to a US Department of Energy report, wind energy could generate up to 20% of the nat …

Coercivity of Neodymium Magnets Permanent magnets radiate magnetic fields and do not require an outside source of magnetism. Their materials will take on the properties of a strong magnetic field when exposed to it. The magnet continues to emit a magnetic field after the initial field is withdrawn. Resistance to demagnetization is one of the most useful properties for a magnetic material. A high-quality permanent magnet should emit a high magnetic field with a low mass. It should …
