    Question

    The condition for the phenomenon of electromagnetic induction is that there must be a relative motion between:

    1. The galvanometer and magnet
    2. The coil of wire and galvanometer
    3. The coil of wire and magnet
    4. The magnet and galvanometer

    Hint:

    Electromagnetic induction requires a relative motion between the coil and the magnet.

    The correct answer is: The coil of wire and magnet

      The condition for the phenomenon of electromagnetic induction is that there must be a relative motion between the coil of wire and the magnet.
      • Electromagnetic induction occurs when there is a relative motion between the coil and the magnet.
      • The relative motion induces an electromagnetic field.
      • Thus current flows in the coil as a result of electromagnetic induction.
