Mutual induction happens in:
Correct answer: D. Transformer
- A. AC generator
- B. DC generator
- C. Battery
- D. Transformer
Explanation
Mutual induction is the ability of an inductor in one circuit to induce a voltage in another circuit. When a transformer primary has alternating current flowing in the conductor, magnetic flux surrounds the conductor in proportion to the amount of the current.

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.
