Question

Magnetisation (M) of a material depends on megnetising field (H) according to following graph:
If same variation is studied at higher temperature then slope of the above graph will:

• A. Remain same
• B. Increase
• C. Decrease
• D. may increase and decrease

Answer 1

The correct option is A Remain same

Explantion:

Temperature affects magnetism by either strengthening or wreaking a magnet's attractive forces.But, at any temperature , the relation between magnetism and magnetising field remains the same.

Therefore , At higher temperature, slope of the graph will remain the same.

Hence , A is the correct option.
