  2. 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 .

  3. Neodymium - Wikipedia

    en.wikipedia.org/wiki/Neodymium

    A neodymium magnet of a few tens of grams can lift a thousand times its own weight, and can snap together with enough force to break bones. These magnets are cheaper, lighter, and stronger than samarium–cobalt magnets. However, they are not superior in every aspect, as neodymium-based magnets lose their magnetism at lower temperatures [52 ...

    During the 20th century, the maximum energy product of commercially available magnetic materials rose from around 1 MGOe (e.g. in KS Steel) to over 50 MGOe (in neodymium magnets). [4] Other important permanent magnet properties include the remanence ( B r ) and coercivity ( H c ); these quantities are also determined from the saturation loop ...

  8. Rare-earth magnet - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_magnet

    Ferrofluid on glass, with a rare-earth magnet underneath. 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.
