Powerful magnet demagnetization method can be powerful magnet magnetization and demagnetization, because itself is or will bring some magnetic magnet, so we can according to the use of powerful magnets is different to make certain methods for demagnetization method. Vibration demagnetization method: this method is simple operation is a powerful magnet for strong intense shaking, again after the operation of the vibration of magnet inner structure has changed, and transform the physical of the magnet is generally adopt this way the demagnetization method the effect is not big, only a small amount of demagnetization can temporary use. High temperature demagnetization method: 2. High temperature demagnetization method of main is put into operation in the high temperature furnace for heating, after high temperature treatment will be powerful magnet magnetic eliminate, but in the process of heating for the effect of high temperature will directly result in magnets inside the change of the structure of the object changes, so the demagnetization method generally used for magnet for scrap and recycling. Communicate magnet demagnetization method: this is about the magnet demagnetization way into can produce ac magnetic field in space, after ac magnetic field, the magnet internal structure will be upset, which can achieve the effect of demagnetization, using this method is more common demagnetization method. The above three methods for strong magnet demagnetization is valid, but we still preferred to communicate during the demagnetization method than the effect of high temperature demagnetization method and vibration demagnetization method is good demagnetization of high efficiency, is the most used in industrial production methods.
