Ferrofluid

Ferrofluid | Magnetic Domain Visualization Fluid

Ferrofluid (Ferrotec EFH-1) is for magnetic domain visualization only, and should not be used as speaker fluid. Ferrofluid is a liquid made of nanoscale magnetic particles suspended in a oil based carrier fluid. Each tiny particle is coated with a surfactant to inhibit clumping. This allows Ferrofluid to respond dramatically to the influence of magnetic fields and change back when the magnetic influence is taken away. Care should be taken to keep the fluid away from oxygen, as it will oxidize over time.
