Question

Explain the concept of magnetic hysteresis? What do you mean by area of hysteresis loops?

Answer 1

Hysteresis. When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called a hysteresis loop.

I hope this will help you

Answer 2

Answer:

The hysteresis loop shows the relationship between the intensity of magnetization and the magnetizing field. The loop is generated by measuring the magnetic flux coming out from the ferromagnetic substance while changing the external magnetizing field.
