Neodymium magnets are a type of rare earth magnet. Rare earth magnets are a class of magnets that are made from rare earth elements and are known for their strong magnetic properties. Neodymium magnets, also known as NdFeB magnets or Neo magnets, are the most powerful type of permanent rare earth magnets.
Neodymium magnets are made from an alloy of neodymium, iron, and boron, and are known for their high energy and strong magnetic fields. They are commonly used in a variety of applications, including electric motors, generators, loudspeakers, and magnetic resonance imaging (MRI) machines.
There are other types of rare earth magnets in addition to neodymium magnets, including samarium-cobalt magnets and cerium-iron-cobalt magnets. These magnets are also made from rare earth elements and have strong magnetic properties, but they are not as powerful as neodymium magnets.
