Physical Properties of Permanent Neodymium Magnet:
a) Industrial use of NdfeB magnets was widely for voice coil motors,high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers,etc.
b)NdFeB magnets have a moderately high Reversible Temperature Coefficient of Induction which reduces total magnetic output as temperature rises. Selection of NdFeB magnets instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.
c)NdFeB magnets have some limitations due to their corrosion behavior. In humid applications, a protective plating is highly recommended. Platings which have been used successfully include, parylene,epoxy resin,zinc plating, gold plating, Ag plating,nickel plating and combinations of these platings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance.
