Rare earth neodymium magnets, also known as NdFeB magnets or Neo magnets, are made from an alloy of neodymium, iron and boron. They have excellent magnetic property and are extremely strong for their small size. Neodymium magnets are permanent, and have a high maximum magnetic energy. Due to high ratio of performance over price, neodymium magnets has become extremely popular in almost all applications that require high performance magnets such as motors, sensors, computers, home appliances, craft model etc.
