What is Ferrofluid? In short, it is a liquid that responds to magnets andmagnetic fields. The longer answer is ferrofluid is an extremely fine powder,coated with a soap-like material called a surfactant, suspended in a mineraloil liquid base. The resulting magnetic suspension is called a ferrofluid.When no magnetic field is present, ferrofluid behaves and flows like a normalliquid. However, when a magnet or magnetic field is introduced, the ferrofluidis attracted to the field. Spikes then form along the magnetic field lineswhen the magnetic surface force exceeds the stabilizing effects of fluidweight and surface tension. Note: The ferrofluid leaves permanent stains to fabric, pvc counter andfurniture. the ferrofluid will also be attracted to magnets when close to it.Please operate carefully to avoid spills.
