Neodymium Iron Boron (NdFeB) magnets, also known as neodymium magnets, are the most widely used type of rare-earth magnet and are known for their exceptional magnetic strength and versatility. They are composed of an alloy of neodymium, iron, and boron, and are characterized by their extremely high magnetic properties. NdFeB magnets have the highest energy product of any material today and are available in various grades, shapes, and sizes to suit a wide range of applications.
