Ferrite magnet belong to sintering permanent magnet materials. It composed of Ba and SrFe. This magnetic materials can resist demagnetization and have advantage in low cost. Ferrite magnet is stiff but brittle so it needs special mechanical working. Its anisotropic magnet because of magnetic direction according to manufacture orientation should be charged magnetism on the basis of direction adopted. But its isotrpic magnet dosen't have a tropism and can be charged magnetism in any direction. BH is rangeing from 1.1 MGOe to 4.0MGOe. Ferrite materials are vastly applied from moter, loudspeaker to toy and crafts, Thus it is the main permanent magnetic material widely used so far.
