Rare Earth Magnets 

Rare earth magnets, also known as neodymium magnets, are the strongest magnet made of rare earth elements. There are sixteen types of neodymium magnets on the periodic table of the elements. Neodymium magnets come in a variety of shapes and sizes, such as round, cubed, square, rectangular, or ring-shaped. Some neodymium magnets operate only in dry environments, and may lose their magnetic fields at high temperatures. Some neodymium magnets have corrosion-resistance, and can have a high resistance to demagnetizing. Rare earth magnets have a holding power, expressed in pounds. Neodymium iron bore (NdFeB) is a type of neodymium rare earth magnet that has a permanent holding. Rare earth magnets come in various grades such as N52, N42, and N45. Gauss rating of neodymium magnets determines the speed that the magnets work, and is a magnetism measurement of strength. Neodymium magnets can be found inside of speakers and computers. Rare earth magnets are used by professionals, educators, and hobbyists in science, education, electronics, and craft applications.
