Ferrite magnets

A magnet made from magnetic oxides whose primary component is Fe₂O₃. In practical magnets, barium and strontium are included, so these magnets are also called barium ferrite magnets or strontium ferrite magnets. Features of these magnets include that the primary components are iron oxides, they are inexpensive, they have high corrosion resistance, they have high electrical resistivity, etc. However, their magnetic characteristics are lower than those of rare earth magnets and their maximum energy product is about 1/10 of that for a rare earth magnet.
