    Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. 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.

    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 ...

    en.wikipedia.org/wiki/Talk:Neodymium_magnet

    The "N, ND, or NS" prefix usually means Neodymium Iron Boron magnet alloy and the "Grade/number value" suggests that the alloy has a Maximum Energy Product of 38 MGOe. This magnetic characteristic is volume independent and only gives you an idea of what the net magnetic field of a magnet with a particular geometry will be.

  6. Superconducting magnet - Wikipedia

    en.wikipedia.org/wiki/Superconducting_magnet

    Superconducting magnet. Schematic of a 20-tesla superconducting magnet with vertical bore. A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger ...

  7. Tesla (unit) - Wikipedia

    en.wikipedia.org/wiki/Tesla_(unit)

    The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre. The unit was announced during the General Conference on Weights and Measures in 1960 and is named [1] in honour of Serbian-American electrical and ...
