What is ferrite magnets

Ferrite magnets are a large class of magnets that include chemical compounds such as hematite (Fe23) and magnetite (Fe3O4), which is the most magnetic naturally occurring mineral on Earth. Every ferrite magnet is a ceramic, and of course a magnet, meaning it attracts other ferromagnetic materials and attracts or repels other magnets. A ferrite magnet is the most simple type of magnet, in contrast to more sophisticated magnets like Alnico magnets or neodymium magnets (rare-earth magnets). Ferrite magnets are permanent magnets, unlike electromagnets which are only magnetic when supplied with an electric current.Ferrite magnets, also known as ferromagnetic materials, are generally classified into two categories based on their magnetic coercivity, or persistence of internal magnetism: soft ferrites and hard ferrites. These categorizations do not refer to the actual hardness of the magnets -- both types are brittle ceramics -- but rather their magnetic coercivity. Depending on whether a magnet is soft or hard, it may have different applications. For instance, a hard ferrite magnet might be used in a radio or a hard disk. A soft ferrite magnetic would be used as a transformer core or an electromagnet core.Ferrite magnets are used often used as permanent magnets or as ferrite cores for electromagnets. Ferrite magnets are non conductive (meaning they do not transmit electricity). Ferrite magnets are magnets that are a mix of ceramic materials and chemicals, with iron oxide as its primary ingredient. However, they can contain a mix of oxides from other metals as well.
