2. Ferrite (magnet) - Wikipedia

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

   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 ...

3. 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 ...

   Each layer is about 5 mm thick. It reduces the effect of the Earth's magnetic field inside by a factor of 1500. Mu-metal is a nickel – iron soft ferromagnetic alloy with very high permeability, which is used for shielding sensitive electronic equipment against static or low-frequency magnetic fields.

6. 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 ...

7. Neodymium magnet - Wikipedia

   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.
