www.kbcc.cuny.eduMagnets are materials that produce a magnetic field of their own. Extreme examples of magnets are (1) "hard" or "permanent" magnets (like refrigerator magnets), which remember how they have been magnetized, and (2) "soft" or "impermanent" magnets (like the material of the refrigerator door), which lose their memory of previous magnetizations.
