Description: A sealed glass tube filled with iron flings may be used to demonstrate magnetization of a ferromagnet. Shake the filings into the long thin section of the tube. Magnetize the filings by ...

Iron fillings reveal a magnet's magnetic field. You can see a magnet's magnetic field by scattering tiny iron filings around it. The iron filings form a pattern that reveals the lines of the ...

Magnets are also surrounded by a similar three-dimensional field. This can be "seen" in two dimensions if iron filings are sprinkled on a sheet of paper placed over the magnet. The filings align ...
