neodymiumijzerboride
Neodymium iron boride, often abbreviated as NdFeB, is a permanent magnet material. It is a rare-earth magnet, meaning it is composed of elements from the rare-earth group, specifically neodymium. These magnets are known for their high magnetic strength relative to their size. They are manufactured through a process that involves melting and casting an alloy of neodymium, iron, and boron. The resulting material is then pressed and sintered, followed by magnetization. The precise composition and manufacturing process can be tailored to achieve specific magnetic properties.
NdFeB magnets are the strongest type of permanent magnets commercially available. Their coercivity, which is the
