_is the energy expended to magnetize and demagnetize the core material in each cycle of the A.C..
Correct answer: B. Hysteresis loss
- A. Power loss
- B. Hysteresis loss
- C. Heat loss
- D. All of the above
Explanation
Some of the energy is wasted in magnetization and demagnetization of core due to a.c. This is called hydsteresis loss. It is minimized by taking a soft iron core.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
