Question

Give some important and summary about Demagnetization magnets

Answer 1

The field strength required for the demagnetization must be of opposite polarity (reversing) to the magnetization field strength H sat, hence -H c. The demagnetization with reversing field H c only works on a magnetized material sample of simple, symmetrical geometry. Technical parts with irregular geometry and made of materials with different magnetic properties (for example hardened parts) must be demagnetized.

Step-by-step explanation:

Answer 2

When a magnetized magnet is exposed to a strong magnetic field that is set up in opposition to the magnet's magnetization, a portion of the magnet may become demagnetized.

This demagnetization essentially reduces the magnet's effective field, and the magnet's performance suffers as a result.
