What kind of magnet is a fridge magnet

Ferrite Magnets (ferromagnetic or ferrimagnetic) are the kinds of magnets in a fridge magnet. A refrigerator magnet is made of powdered ferrite (iron rust) and a liquid binding agent of plastic or rubber. The two are heated, mixed together, and poured into a sheet mold which is then exposed to a strong magnetic field.
