Question

What is the formula to obtain the hysteresis loss devised by Steinmetz?

(a) hysteresis loss = hysteresis coefficient / frequency of magnetization * (maximum flux density)^steinmetz coefficient

(b) hysteresis loss = hysteresis coefficient * frequency of magnetization / (maximum flux density)^steinmetz coefficient

(c) hysteresis loss = hysteresis coefficient * frequency of magnetization * (maximum flux density)^steinmetz coefficient

(d) hysteresis loss = 1/hysteresis coefficient * frequency of magnetization * (maximum flux density)^steinmetz coefficient

The question was posed to me in an online quiz.

I would like to ask this question from Determination of Iron Losses & Slot Leakage topic in portion Principles of Magnetic Circuit Design of Design of Electrical Machines

Answer 1

The correct choice is (c) hysteresis loss = hysteresis coefficient * frequency of magnetization * (maximum flux density)^steinmetz coefficient

Easy explanation: The hysteresis coefficient along with the frequency of magnetization and maximum flux density is calculated first. Next the Steinmetz coefficient is calculated and on substitution it gives the hysteresis loss.
