Cars with neodymium-Iron-Boron magnets

Automobile industry is one of neodymium-Iron-Boron magnets are widely used in areas. In each car, 30 parts using magnets in General. It is said that the number of micro-motor using magnets in foreign luxury cars have up to 70 to complete various control actions on the car. Now an annual output of 55 million vehicles around the world, and per computer using neodymium-Iron-Boron magnet motors from the current average of 20 by 2012, increasing to 30, estimates had to be neodymium-Iron-Boron magnet motors will increase from the current 800 million to 1.6 billion. As cars to small, lightweight and high performance direction, increasing demand for the car magnets that are used in the performance, which will accelerate the development of ND-Fe-b magnets. If, neodymium-Iron-Boron magnets 50% increase in cars, each car will need 102g, calculated according to the above global annual output of 55 million cars requires anisotropic ND-Fe-b magnet is approximately 5600T.
