To demagnetize a rotor, you can use an alternating magnetic field method, where the rotor is exposed to an alternating current (AC) magnetic field that gradually decreases in strength. This process disrupts the magnetic domains within the rotor material, effectively reducing its magnetism. Another method involves heating the rotor above its Curie temperature, causing the magnetic properties to be lost. It's essential to handle the rotor carefully during these processes to avoid damaging it.

How to demagnetize a magnet?

To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.


What does demagnetize mean?

Demagnetize means to remove the magnetism from an object, causing it to lose its magnetic properties. This can be done by exposing the object to a magnetic field in the opposite direction to cancel out the existing magnetization.
