Ring Neodymium MagnetsPermanent Magnet MaterialsIntroduction
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 andrare earth magnets. The non-rare earth magnets include Alnico magnets and Ceramicmagnets. Rare earth magnets include Sm-Co magnets and NdFeBmagnets(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 alarge 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 achallenge to any user. Abalance between cost and performance must be considered in selecting of permanent magnet material. In Reference Information section of this page, several reference books are listed. Following is aComparison Table to help you select aright permanent magnet material for your applications.
