Iron filings and bar magnets work together to make an amazing demonstration of magnetic fields. When they are separated by a piece of paper or a sheet of Plexiglas, the filings align with the magnetic field of the bar magnet in a dramatic way. However, if you are not careful, you can easily end up with a bar magnet covered with iron filings.

Pinch off as many of the filings as possible with your fingers.

Press a sticky substance, such as wax or adhesive tape, against the iron filings.

Remove the sticky substance from the magnet.

Repeat using a clean spot on the sticky substance until all iron filings are removed.
