Ferrite

Ferrite magnets, also known as ceramic magnets, were developed in the 1960’s as a low cost alternative to metallic magnets. Ferrite magnets have won wide acceptance due to their excellent corrosion resistant and good resistance to demagnetization. Despite their relatively low energy output, ferrite magnets’ popularity is largely from its low price. It is the first choice for most automotive sensors, MRI machines, DC motors, and magnetic separators. In fact, based on weight, it is the most widely used permanent magnet available today.
