Question
Electromagnetic induction i.e., currents can be induced in coils
- Only if the coil moves
- Only if the coil moves and magnet also moves in the same direction
- Only if the magnet moves
- 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.
