Ndfeb magnet magnetization and demagnetization is able to do, due to the powerful magnet itself is or will bring some magnetic, so we can according to the difference under the condition of the application of the ndfeb magnet demagnetization to make certain.
Vibration demagnetization method: the actual operation is very easy to strong magnet demagnetization way to super intense shaking, through strong shock again after the operation of the magnet structure produced change, and change the strong magnet physical this method into usually adopt the mode of this kind of demagnetization effect is not big, can only a small amount of demagnetization to temporary application.
High temperature demagnetization method: high temperature demagnetization method key operation method is to throw in a strong magnet in the high temperature furnace for heating, through high temperature processing can remove magnetic ndfeb magnet, just in the process of the operation of the heating due to the effect of high temperature can cause magnet and internal changes in the structure changes of the object, and using this kind of demagnetization method usually used for scrap and recycling of strong magnet.
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.
After disconnecting the previous: for magnet magnetic phenomena under a: what are the factors affect the price of the magnet?
