Vials of a number of compounds (NaCl, MnSO4, FeSO4, CoCl2, NiSO4, ZnSO4, K4Fe(CN)6, [Co(NH3)6]Cl3, [Ni(NH3)6]Cl2, and H2O) are hung from a thread. When a magnet is brought near, some of the vials are attracted.

Manganese(III) oxide, with 4 unpaired electrons per Mn atom, is more strongly attracted to a magnet than is manganese(IV) oxide, with only 3 unpaired electrons per Mn atom. Potassium permanganate, a compound of Mn(VII), has no unpaired electrons and is not attracted to a magnet.

A magnet is shown to strongly attract a pair of metal tongs. The magnet has no visible effect on liquid nitrogen, but when pale blue liquid oxygen is poured near the poles of the magnet, it shows definite attraction.
