Magnet Materials IntroductionPermanent 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 MaterialsEach 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. In Reference
Information section of this page, several reference books are
listed. Following is a Comparison Table to help you select
a right permanent magnet material for your applications.
