neodymium magnetsPermanent 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.Parameter of Neodymium MagnetsMaterialMagnetic
