Also known as Iron Filings. The most common uses include electromagnetism experiments, chemistry experiments, art works, Powder metallurgy, fire works (sparklers), concrete additive, and sand blasting.
Students use iron filings to draw or reveal the magnetic lines as well as the strength and the direction of the magnetic forces.
In electromagnetism science experiments iron powder is used to assess and compare the strength of electromagnets. The most iron filing is lifted - the stronger a magnet is.
Iron filings are also used to make magnetic puttys, magnetic toys, artistic drawings, magnetic paint, heavy concrete, magnetic plastic parts and more.
