|(I) Introduction to ferrite magnet:|
|They offer an excellent cost performance ratio and are made mainly from Fe2O3 (iron oxide) and BaCO3 (barium carbonate) or SrCO3 (strontium carbonate). These magnets are formed by powder metallurgy.
There are two types of magnet: the isotropic magnet, molded in the absence of a magnetic field and the anisotropic magnet, which has outstanding properties in the direction of the field.
Two types: dry and wet pressed
With their high coercive force ferrite magnets are difficult to demagnetise when subjected to an external magnetic field.
Because the properties listed in underneath table change some-what with the shap and size of the magnet, magnet properties are usually set by consultation with the client
