Permanent magnets are used in a wide variety application in all industries but they can all be classified into one of the sections below:-
Conversion of Electrical Energy to Physical Motion Strong Special NdFeB Magnets
Actuators, speakers, motors, meters and other instrumentation.
Conversion of Physical Motion into Electrical Energy
Generators, microphones and sensors.
Producing Mechanical Energy
Holding, lifting, attracting, repelling, conveying, driving & separating
Controlling Fields
Annealing, plasma control, sputtering, focusing & NMR.
Mechanical to Heat
Eddie Current and Hysteresis drives

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. They have replaced other types of magnets in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.

There are two principal neodymium magnet manufacturing methods:

Classical powder metallurgy or sintered magnet process
Rapid solidification or bonded magnet process
Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
