2. Rare-earth magnet - Wikipedia

   en.wikipedia.org/wiki/Rare-earth_magnet

   A rare-earth magnet is a strong permanent magnet 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. The magnetic field typically produced by rare-earth ...

3. Samarium–cobalt magnet - Wikipedia

   en.wikipedia.org/wiki/Samarium–cobalt_magnet

   A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt . They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton. In particular, Strnat and Ray developed the first ...

4. Electropermanent magnet - Wikipedia

   en.wikipedia.org/wiki/Electropermanent_magnet

   An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material.

5. Neodymium magnet - Wikipedia

   en.wikipedia.org/wiki/Neodymium_magnet

   A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet. [2] Developed independently in 1984 by General Motors and in 1970s by Sumitomo Special Metals ...

6. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   A stack of ferrite magnets, with magnetic household items stuck to it. A ferrite is one of a family of iron oxide -containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are not electrically ...
