How to remove the magnetism from iron?

The demagnetization effect is generally used more often in the analysis of motor loads.

The demagnetization effect is generally used more often in the analysis of motor loads. The main statement is that the armature reaction has a demagnetizing effect. It means that the magnetic field generated by the load current is in a different direction than the magnetic field generated by the armature winding and has the effect of weakening the strength of the magnetic field generated by the armature winding. When analyzing the working principle of a transformer, the counteracting effect of the magnetic field generated by the secondary winding current on the magnetic field generated by the primary winding is also called the demagnetizing effect.

If you do not know much about the principle of motors and transformers, you can also literally understand that the so-called "demagnetization effect" is a phenomenon that produces a magnetic field in the opposite direction of the original magnetic field, with the size of the original magnetic field offset.

The reason for the magnetization of a magnet is as follows: the electrons rotating around each nucleus are seen as a current, and the current generates a magnetic field, and when the direction of the magnetic field is more or less in the same direction (related to the arrangement of the atoms), the whole object exhibits magnetism. The principle of demagnetization is to disrupt the arrangement of the nuclei (vibration, heating to intensify their thermal motion, etc.) so that the atoms are disordered and the magnetic fields cancel each other out and the whole object does not show magnetism.
