Ceramic magnets are made from synthetic material and are also called ceramic ferrite or graphite magnets. These are manufactured from oxides of Ferric and Barium (or Strontium) with certain doping agents, which differ from manufacturer to manufacturer.
The different uses of Ceramic magnets are:
•These are used in the communicative materials such as in loud speakers, microphones, bells, inductors and receivers.
•The electrical materials like cycle dynamos, D. C. (Small) motors, instruments and toy-motors also use the ceramic magnets.
•The electronics items like the calculators, computers and tabulators uses the ceramic magnets.
•The ceramic magnets are used in transportation items such as car radios, aerial motors and dynamos for autos, magnetoes for motor cycles and scooters.
•Some other miscellaneous use of ceramic magnets can be seen in belts, door-latches, filters, magnetic-chucka mngnetic games magnetic separators, novelties, plastic materials and stationery items.
The Ceramic or Ferrite magnets possess the following benefits:
•These have considerably higher coercive force and retention of magnetism for a very long time.
•The ceramic magnets are highly stable to demagnetising field and temperature changes.
•The ceramic magnets have about 60 per cent weight as compared to metallic magnets.
•These are available at lower costs.
•No `keepers` necessary for long preservation of the ceramic magnets.
But the ceramic magnets are very fragile in nature and can break easily if falls down. Therefore, excellent care should be taken of these types of magnets especially to avoid chipping of sharp edges or corners.
