Samarium cobalt is a type of rare-earth magnet that has the ability to withstand and operate in high temperatures, however they are not as powerful as super-strong neodymium magnets. Because of their high maximum operating temperature they are commonly used in applications such as motors and electric motors, turbo machinery and sensors. Ring magnets are very versatile and are also used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more.
