DISK FERRITE MAGNETS ALSO KNOWN AS CERAMIC MAGNETS, ARE YOUR BEST ALL-ROUND PRACTICAL MAGNETS AVAILABLE.
They are made from strontium or barium ferrite.
Hard ferrites have high coercivity, so are difficult to demagnetize, an essential characteristic for a permanent magnet.
They are very stable and difficult to demagnetize and can be made with both high and low coercive forces. They come in first as a choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors. Ferrite magnets must be magnetized in the direction of orientation, which is the same as the direction of pressing.
Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity.
Ferrite magnets are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors, also used as switches in refrigerators, air conditioners, etc. Isotropic Square Block Plate Ceramic Permanent Magnets C8 75X75X15mm
What is a ceramic magnet?
Ceramic magnets (also known as ferrite magnets) were developed in the 1960’s as a low-cost alternative to metallic magnets. While their hard, brittle quality and low energy exclude them from some applications, ceramic magnets have won wide acceptance due to their corrosion and demagnetization resistance, and low price per pound. Ferrite represents more than 75 percent of world magnet consumption by weight. C5 Circular Round Ceramic Permanent Magnets Anisotropic for Craft, Bulk Wholesale Anisotropic Ceramic Magnets
Who uses ceramic magnets?
Ceramic magnets are the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors. They are also widely used in craft and hobby projects, and hold a large percentage of the world’s refrigerator magnets! Additionally, they appear in many educational science kits and are great for a demonstration of magnetic attraction and repulsion.
