Q A: Hematite Magnets | Department of Physics ...

When heated enough, hematite becomes a paramagnet, in which the atomic magnets just randomly point all different directions. Anyway, although hematite is weakly magnetic (and hence can be attracted to your magnet), its magnetism is "soft", meaning that its domains don't stay lined up when the magnetic .
