  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. [2] Developed independently in 1984 by General Motors and in 1970s by Sumitomo Special Metals ...

  3. 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 ...

  4. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    Scientists. v. t. e. In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. It is the ratio of the magnetic induction to the magnetizing field as a function of the field in a material.

  5. Superconducting magnet - Wikipedia

    en.wikipedia.org/wiki/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 electric currents than ...

  6. Staple (fastener) - Wikipedia

    en.wikipedia.org/wiki/Staple_(fastener)

    A staple is a type of two-pronged fastener, usually metal, used for joining, gathering, or binding materials together. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach pieces of paper together; such staples are a more ...

  9. 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 ...
