The magnet was used at a very early stage in China and Greece for orientation purposes. Now-a-days it is likewise to orientate in a different areas with the help of magnetic strength? for example in form of a compass. However, its important features were only examined thoroughly in the 17th Century. The highest concentration appears on the Pole! If you separate it into two pieces, you would have two magnets with also one South Pole and one North Pole. As the Earth’s magnetic field, which allows the orientation of the compass, has a north pole and a south pole.
NdFeB magnet, Neodymium magnet is an alloy magnet made from Nd, Fe, B and other metal elements,
which has the high remanence, high coercive force,
high energy and high performance/cost ratio.
Applications of Neodymium Magnets: magnetic buttons, micro-special electric machinery, audio equipments, permanent-magnet instrumental meters, electronic industry, auto industry, nuclear magnetic resonance equipments, magnetic suspension system, magnetic transmission gears and magnet therapy equipment, aero generators, loudspeakers, magnetic separators, magnetic separators, copiers, synchrotrons, radiation sources, free electron lasers, nuclear industry.
