How do you remove magnetism or electricity from metal?
Magnetization is to make the magnetic domains of the magnetic domains in the magnetic material become uniform. When the material that does not exhibit magnetism is placed into another strong magnetic field, it is magnetized, but not all materials can be magnetized, and only a few metals and metal compounds can be magnetized. Magnetic materials are divided into many tiny regions, each of which is called a magnetic domain, each of which has its own magnetic distance (i.e., a tiny magnetic field). Generally, the magnetic distances of each domain are different, and the magnetic fields cancel each other, so the whole material is not magnetic. When the direction of each domain is uniform, the whole material shows magnetism.
Degaussing: when the magnetized material, influence of external energy, such as heat, impact, the domain which the magnetic moment direction will become inconsistent, magnetism will be weakened or disappeared, this process is called degaussing.
The method is heating, energy absorption metal heating energy will increase the free electron motion of the electron acceleration disturb electronic arrangement was neat, cooling down after the electron cannot restore the original order arrangement of the state will let the loss of magnetic metal.
