Samarium Cobalt Rare Earth magnets (also known as SmCo magnets) are another type of permanent magnet. A big advantage of SmCo magnets is that they can operate at temperatures up to 300 degrees Centigrade. SmCo magnets are widely used in applications in which high operating temperature and high corrosion and oxidation resistance are crucial.
