Square powerful magnets expert describes high temperature demagnetization method communicate with magnet demagnetization method
Square powerful magnets expert describes high temperature demagnetization method communicate with magnet demagnetization method no matter what material made of square powerful magnets, is to have the same properties of hard and brittle.
May be some people don't understand, what will hard brittle?
This is very simple if you have a rectangular magnets you can give it a try.
Using ordinary iron products in the square magnet surface force, also can draw the walls white mark, and for the use of rectangular magnets and no impact, this means that the square magnet material is very hard.
But said it is very fragile, we all have experiences, may inadvertently on the ground, square magnet will break into pieces, this is because the square magnet material form is not merely composed of metal elements, so attention should be paid to prevent knock against on maintenance, split or filler filling can be effective protection.
High temperature demagnetization method: high temperature demagnetization method mainly 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.
