Products Overview

Adams offers Samarium Cobalt magnets in square and rectangular blocks. Samarium magnets can be used for high-temperature applications where neodymium will not work.

Features include:

• They have high magnetic properties and are resistant to demagnetization

• Samarium cobalt magnets offer good thermal stability

• Samarium cobalt magnets are resistant to corrosion

• Samarium cobalt magnets are hard and brittle and may chip or break if dropped.

Applications for Samarium Cobalt

High-performance permanent magnet motors, medical instruments, magnetic couplings, magnetic bearings, gyroscopes, accelerometers, voice coil motors, particle accelerators, sputtering deposition, Halbach arrays, magnetic separation devices, speakers, microphones, undulators, wigglers, particle beam focusing devices, and many others. 

Demagnetization Curves

A second quadrant demagnetization curve provides information about the magnetic characteristics of a magnet, including the magnetic field strength and how resistant it is to demagnetize. How it is used in a magnetic circuit will affect its performance. When a permanent magnet is fully magnetized, its magnetic domains are aligned. Certain conditions such as temperature and reverse magnetic fields can cause some of the domains to lose this alignment and reverse, triggering the magnet to lose some or all of its magnetic field.
