Arc Magnet
Arc magnets are a unique shape which are designed especially for motors, generators and alternators and are commonly used for both rotors and stators. They are also used in magnetic flywheel assemblies. In motor design a ring of magnets with alternating polarities on the inner radius rotate in close proximity to a number of copper coils. As the copper passes through the magnetic fields an electric current is induced within the copper.
Neodymium Arc Magnets are typically used in permanent magnet motors, generators and torque couplings. However, these may be found with sensors and holding applications.
Grades of Neodymium
Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH.
Demagnetization
Rare Earth magnets have a high resistance to demagnetization, unlike most other types of magnets. They will not lose their magnetization around other magnets or if dropped. They will however, begin to lose strength if they are heated above their maximum operating temperature, which is 176°F (80°C) for standard N grades. They will completely lose their magnetization if heated above their Curie temperature, which is 590°F (310°C) for standard N grades. Some of our magnets are of high temperature material, which can withstand higher temperatures without losing strength.
