Hard Anisotropic Ferrite Magnet Ceramic magnets (also known as "ferrite" magnets) are part of the permanent magnet family and are currently the lowest cost hard magnets. The ceramic (ferrite) magnet composed of strontium carbonate and iron oxide has medium strength and can be used at quite high temperature.
