3. 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 .

4. Magnet - Wikipedia

   The ferrite magnets are mainly low-cost magnets since they are made from cheap raw materials: iron oxide and Ba- or Sr-carbonate. However, a new low cost magnet, Mn–Al alloy, [ 36 ] [ non-primary source needed ] [ 42 ] [ 43 ] has been developed and is now dominating the low-cost magnets field.

5. Plastic magnet - Wikipedia

   en.wikipedia.org/wiki/Plastic_magnet

   A plastic magnet is a non-metallic magnet made from an organic polymer. Plastic magnets could be used in computer hardware such as disc drives , as well as in medical devices such as pacemakers and cochlear implants , where the organic material is more likely to be biocompatible than its metallic counterparts.

6. Electromagnet - Wikipedia

   en.wikipedia.org/wiki/Electromagnet

   (A non-circuit example would be a magnet with a straight cylindrical core.) To determine the force between two electromagnets (or permanent magnets) in these cases, a special analogy called a magnetic-charge model can be used. In this model, it is assumed that the magnets have well-defined "poles" where the field lines emerge from the core, and ...

7. Exchange spring magnet - Wikipedia

   en.wikipedia.org/wiki/Exchange_spring_magnet

   The exchange spring magnet offers a geometry able to improve upon the previously reported maximum energy products of materials such as Rare Earth/Transition Metal complexes; while both materials have sufficiently large H C values and operate at relatively high Curie Temperatures, the exchange spring magnet can achieve much higher M sat values ...
