Question

Point out the wrong statement about the magnetic properties of soft iron and steel. (A) Retentivity of soft iron is more than retentivity of steel (B) Coercivity of soft iron is less than coercivity of steel (C) Area of B-H loop in soft iron is smaller than the area of B-H loop for steel (D) Area of B-H loop in soft iron is greater than the area of B-H loop for steel

The B-H curve of both soft iron and steel are shown in figure. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/5d60e30aebdddea38ba05291bfcebdc2-.jpeg" /> From the above hysteresis curve it is clear that area of B-H loop in soft iron is smaller than that of steel.

Q. 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

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.
