Operating Temperatures of Different Permanent Magnets
Posted by Admin
Here are the operating temperatures and Curie temperatures of some of the most commonly used permanent magnets. Yet, it’s important to note that the actual operating temperature of a permanent magnet will depend on a variety of factors, including its size, shape, and the strength of the magnetic field it is exposed.
Neodymium Iron Boron (NdFeB) Magnets
NdFeB magnets are the strongest type of permanent magnets available and are commonly used in motors, generators, and other industrial applications. These magnets have a maximum operating temperature of approximately 150°C and a Curie temperature of about 310-400°C.
