How many types of magnet
WebA rare earth magnet is a magnet made from one of the rare earth elements (of which there are 17) in the Lanthanide series of metals in the periodic table. The two most common rare earth magnets are Neodymium (Nd-Fe-B) and Samarium Cobalt (SmCo). Read more about these two types of magnets. The term “rare earth” can be misleading, because ... Web2 apr. 2007 · Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time. Temporary or soft magnets produce magnetic fields while in the presence of a ...
