FACTS: Ferrites are ceramic materials which exhibit a high degree of magnetic sensitivity. Ferrite material is manufactured by combining certain metallic oxides with a binding agent under high temperature and pressure. Because of their high electrical resistivity and magnetic permeability, magnetically soft ferrites are particularly well suited for the storage, transmission, or reception of magnetic energy. The resistivity of ferrite material also allows those materials to be used in the conversion of electric energy into magnetic energy and vice versa via induction. Because of these…
