Physics Magnetism and Matter Magnet and It's Properties MCQ (Single Correct)

Point out the wrong statement about the magnetic properties of soft iron and steel.

Retentivity of soft iron is more than retentivity of steel.

Coercivity of soft iron is less than coercivity of steel.

Area of B-H loop in soft iron is smaller than the area of B-H loop for steel.

Area of B-H loop in soft iron is greater than the area of B-H loop for steel.

Text Solution

Verified by Experts

The correct answer is:

The B – H curve of both soft iron and steel are shown in figure.

From the above hysteresis curve it is clear that area of B – H loop in soft iron is smaller than that of steel.
