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