Motor magnetic tile exchange coupling role

- Nov 03, 2017 -

There is a strong "exchange-coupling" effect between adjacent electrons in the ferromagnetic mass. In the absence of an external magnetic field, their spin magnetic moments can be "spontaneously" neatly arranged in a small area Up and form a spontaneous magnetization of small areas, known as magnetic tile. In the unmagnetized ferromagnetic material, although each magnetizing tile has a definite spontaneous magnetization direction inside, there is a great magnetism, but a large number of magnetizable magnetizations have different directions so that the entire ferromagnetism is not magnetizable.

When the electromagnetism is in the external magnetic field, the volume of the magnetic tile whose spontaneous magnetization direction and the direction of the external magnetic field are small increases with the increase of the applied magnetic field and further turns the magnetization direction of the magnetic tile to the direction of the external magnetic field.
