How are the strong NdFeB Magnets made out?

　　In driving motor of the hybrid and electric cars, ( Nd-Fe-B ) type sintered NdFeB magnet is an indispensable key component. Compared with other magnets, neodymium magnet not only has strong magnetic force, can be enough to drive the vehicle 's power, but also can reduce motor to make it suitable for the size of the vehicle-mounted use.

　　Well, do you know how the NdFeB magnet is manufactured? It needs first to make alloy containing the necessary material crushed into particles, these particles together forming, and then sintering. Then cut into the required size, which can be completed. This process always feels like making cakes. Of course, in the actual production of high-quality NdFeB magnets, it is not so simple.

　　Not only make particles uniformly into 3～ 5 μM size, but also pay attention to the shape of the uniformity, and also consider the heating sintering method, which will require a lot of time to manufacture.
