2. 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 ...

3. 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.

4. Alnico - Wikipedia

   en.wikipedia.org/wiki/Alnico

   Alnico is a family of iron alloys which, in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym [1] al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets. Before the development of rare-earth magnets in the 1970s ...

5. Bumper sticker - Wikipedia

   en.wikipedia.org/wiki/Bumper_sticker

   A bumper sticker is an adhesive label or sticker designed to be attached to the rear of a car or truck, often on the bumper. They are commonly sized at around 25.4 cm by 7.6 cm (10 in by 3 in) and are typically made of PVC. Bumper stickers serve various purposes, including personal expression, promotion, humor, or political activism.

6. Ferromagnetism - Wikipedia

   en.wikipedia.org/wiki/Ferromagnetism

   Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...

8. 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 ...
