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. What’s more, because they have a superior resistance to corrosion they are ideal for using outside.

Countersunk magnets with opposite poles on the countersunk face can be used to attract two surfaces or two opposing countersunk magnets with the same pole on the countersunk face can be used to create a damping, shock absorbing or repelling effect.
