2. 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 ...

3. 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 ...

4. 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 ...

5. Magnet - Wikipedia

   en.wikipedia.org/wiki/Magnet

   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: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...

6. Ferrite (magnet) - Wikipedia

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

   These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30–160 kiloampere turns per meter (400–2000 oersteds). The density of ferrite magnets is about 5 g/cm 3.
