  1. Question 1

    Q1. A generator converts mechanical energy into electrical energy through electromagnetic induction. What is the role of the rotating coil in the generator?

    • A) The rotating coil generates a magnetic field to induce an electromotive force in the stationary coil.
    • B) The rotating coil induces a magnetic field in the stationary coil due to electromagnetic induction.
    • C) The rotating coil acts as a magnet to attract the stationary coil.
    • D) The rotating coil is stationary, and the magnetic field is generated by the rotating magnet.

    Answer: The rotating coil induces a magnetic field in the stationary coil due to electromagnetic induction.

    Explanation: The rotating coil induces a changing magnetic field in the stationary coil, which generates an electromotive force due to electromagnetic induction.
