Permanent Magnet Materials Introduction:
Permanent magnets are used in the following major groups: acoustic transducers, motors and generators, magneto mechanical devices, and magnetic field and imaging systems. You will find permanent magnets in many products, such as televisions, telephones, computers, audio systems and automobiles.
The permanent magnet family consists of non-rare earth permanent magnets and rare earth magnets. The non-rare earth magnets include Alnico magnets and Ceramic magnets. Rare earth magnets include Sm-Co magnets and NdFeB magnets (Neodymium-Iron-Boron).
Although non-rare earth magnets are used in the majority of these applications due to their economic cost, rare earth permanent magnets have many distinguishing characteristics, such as a large Maximum Energy Product, Two major families of rare earth permanent magnets, Sm-Co magnets and NdFeB magnets.
How to Choose Permanent Magnet Materials
Each permanent magnet material discussed above has its own pros and cons. How to choose the right one for your particular application is a challenge to any user. A balance between cost and performance must be considered in selecting of permanent magnet material.
