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
What is a ceramic magnet?
Sintered Ferrite(Ceramic) Magnets developed in the 1960’s as a low cost alternative to metallic magnets. Although they have low energy (compared with other permanent magnet materials) and are relatively brittle and hard, Ceramic Magnets (Hard ferrite magnets) have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption.
It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
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.
Our ceramic (ferrite) disc magnets come in a many sizes. We recommend using epoxy glue for best results when bonding to other materials. Make sure all surfaces are thoroughly clean and dry. Some applications for ceramic magnets include handcrafts, souvenirs, fridge magnets, whiteboard magnets & educational magnets.
