The value of reverse current which is required by a substance for its demagnetization is called
Correct answer: C. coercive current
- A. hysteresis loss
- B. remanence current
- C. coercive current
- D. relative current
Explanation
The coercive current, also known as the coercive force, is the reverse current required by a substance to demagnetize it completely after it has been magnetized. It is a measure of the material's ability to retain magnetization in the presence of an external magnetic field

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.
