Question

With an increase in the area of hysteresis curve power loss will be

Answer 1

The area under the hysteresis curve is directly proportional to hysteresis loss , that is with the increase in area of the hysteresis curve hysteresis loss also increases, hysteresis curve is a curve drawn between the magnetic field B and magnetic intensity H, this curve can be used to differentiate between soft and hard magnetic materials. Since the loss is proportional to the area of the curve, power loss will increase with the increase in area.
