Do you know how to make out such strong neodymium magnets?

 　　In driven motor of the hybrid and electric cars, sintered NdFeB magnets are indispensable key components. Compared with the other magnet, the magnetic of neodymium magnets is not only strong, but can achieve high power sufficient to drive the vehicle, and the motor can be reduced to the size suitable for vehicle use.

　　Well, do you know how to make out such neodymium magnets? It needs first to make the alloy crushed into particles, which contains the necessary material, together these particles to form certain shape, and then sintered. Then cut into the required size to complete. This process always feels like making a cake.

　　Of course, the actual mass production of high-quality neodymium magnets is not so simple. It needs not only the particles for the reunification of 3～ 5 μM size, but also pay attention to the shape of the uniformity, and consider the heating sintering method, requires a lot of time to manufacture. Through the accumulation of a large number of small technologies can it reach this level of utility.
