What are the demagnetizing methods of magnetic materials? What kind of material does heat treatment demagnetization apply to?
If not, like the 304 stainless steel plate to be heated to 1050 degrees, the rubber glass steel carbon fiber composite material melting point in general are not on the 1000
Molecular magnetic ring current object from inside, we know that the atom by nuclear and electronic components, electronic around the nucleus in the nucleus to form a ring current, other polyatomic molecules with polar molecules, the rotation will form a circular current. The two loop currents form a small magnetic field. The magnetic fields of these molecules are irregular, and the effects are mutually exclusive, so they are not magnetic. There are magnetic substances, and the arrangement of the magnetic fields of the internal molecules has a certain directivity, so the total effect is to produce a macroscopic magnetic field. But the directivity of the magnetic field is very fragile. When the kinetic energy of the molecule increases, it may disturb the ordered arrangement, so that the original field is weakened or disappeared. Shock and heat treatment can increase the kinetic energy of molecules, and may change the original arrangement of magnetic fields, so the effect of demagnetization is formed.
Heating, impact, the magnetic material in the AC field, and gradually weaken the strength of the AC field until it disappears, this material will be erased. Heat treatment is generally used for stainless steel degaussing
