MATERIAL GRADES Ferrites are magnetic ceramic materials composed of metal oxides with Iron oxide as their main constituent. Ferrites have now been firmly established as one of the most important class of magnetic materials and are indispensable in Electrical, Electronics and Communication Engineering. Ferrites which exhibit temporary magnetic properties under the influence of an electrical field are called Soft Ferrites. Soft Ferrites allow easy magnetisation and also rapid reversal of the magnetisation in response to rapid alteration of energising field.
