MAGNET 50X25X12 BAR BLACK

Ferrites are a class of chemical compounds with the formula AB2O4 where A and B represent various metal cations, usually including iron. They are generally composed of iron and barium or strontium oxides. Ferrite magnets are very hard, but brittle ceramic products. They are characterized by a very high normal and intrinsic coercive force, but a rather low residual induction and are virtually free from the effects of a self-demagnetization. They posses a very high electrical resistivity that makes them ideally suited for high frequency applications as the eddy current losses are almost negligible
