ferrite magnets
Ferrite magnets are ceramic anisotropic magnets.
They are made by pressing barium or strontium oxsides
in a magnetic field.
Ferrite magnets are the most commonly used permanent
magnets due to their inexpensiveness and good magnetic
qualities. They also have good temperature and corrosion
resistance. NdFeB-magnets, though, have overtaken ferrite
magnets in some applications where the size-power ratio
is critical.
