Iron, cobalt, nickel, and various alloys of these materials are called ferromagnetic. Ferromagnetic materials can be permanently magnetized through exposure to an external magnetic field. They are strongly drawn towards a magnetic field. Their magnetic...

Ferromagnetism is the effect that creates permanently magnetized materials, such as ordinary horseshoe magnets. Although the effect is most common in pure iron, it can also be reproduced in iron-like substances, including compounds like barium ferrite,...

Ferromagnetism is the "normal" form of magnetism with which most people are familiar, as exhibited in horseshoe magnets and refrigerator magnets. It is responsible for most of the magnetic behavior encountered in everyday life. The attraction between a...
