    Question

    Electromagnetic induction i.e., currents can be induced in coils

    1. Only if the coil moves
    2. Only if the coil moves and magnet also moves in the same direction
    3. Only if the magnet moves
    4. If the relative motion of coil and magnet is present

    Hint:

    A relative motion between the coil and the magnet induces an electromagnetic current.

    The correct answer is: If the relative motion of coil and magnet is present

      Electromagnetic induction i.e., currents can be induced in coils if the relative motion of coil and magnet is present.
      • Current can be induced in coils when a magnet is kept closer to it.
      • A magnetic field is created in the coil when it gets magnetized.
      • The relative motion between the coil and the magnet induces an electromagnetic current.
