Question

Self-demagnetization takes place when opposite poles of a magnet are joined. What is the reason behind this?

Answer 1

Reason is given below.

Explanation:

• The process where the free poles repel one another when self demagnetization takes place at the ends of a magnet so it'll gradually after the alignment of its domain axes.
• The word magnet came from a greek letter word "magnitis lithos".
• A magnet is an object that features a magnetic flux.
• Joining the other poles of a magnet tend to disarrange its parallel magnetic dipoles there by reducing its magnetism.

This is reason for the self-demagnetization when opposite poles of a magnet are joined.
