Ceramic

Ceramic magnets are a very popular magnet. They are an excellent low cost solution for a variety of applications and they are very resistant to demagnetization. Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and arcs for motors. These magnets are usually magnetized through the thickness.
