Question

What is meant by hysteresis? Explain difference in magnetic properties of iron and
steel on the basis of I-H and B-H curves. Derive an expression for the energy loss
due to hysteresi

Answer 1

Explanation:

Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. ... Hysteresis can be found in physics, chemistry, engineering, biology, and economics.
