Ceramic magnet wikipedia.

A force that pulls on other ferromagnetic materials such as iron and attracts or repels other 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. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. The crystallinity of ceramic materials ranges from highly oriented to semi crystalline vitrified and often completely amorphous e g glasses.

Common examples are earthenware porcelain and brick. Rare earth magnets are strong permanent magnets made from alloys of rare earth elements developed in the 1970s and 1980s rare earth magnets are the strongest type of permanent magnets made producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. They are composed of iron oxide and strontium carbonate. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

A magnet is a material or object that produces a magnetic field this magnetic field is invisible but is responsible for the most notable property of a magnet. 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.
