Ceramic magnets are characteristics by very high values of coercive force and are used in preference to Alnico magnets in some applications due to their high resistance to demagnetization and low manufacturing cost. As their name suggest, these are made from metal oxides, such as iron oxide and alkaline earth metal oxides. The ceramic magnets have been used commercially in the construction of cycle dynamos, focussing television tubes, electronic components and toys etc. At present, there is no industrial scale production whatsoever of magnets in India, and entire requirements of ceramic and Alnico types of magnets is being met by imports amounting to about Rs. 70 lakhs per annum involving heavy foreign exchange.
