The combination of iron powder and a horseshoe magnet is a great way to show the patterns of magnetic fields. Simply place some of the iron filings on a piece of paper and move the magnet underneath the paper to see how the powder reacts and aligns to the magnetic field lines. Afterwards, place the powder back inside the re-sealable tube to use again and again. The iconic horseshoe magnet is small enough to fit in your pocket but will still lift an impressive 1kg. Each magnet is protected by a red and silver epoxy paint coating.
