Question
The condition for the phenomenon of electromagnetic induction is that there must be a relative motion between:
- The galvanometer and magnet
- The coil of wire and galvanometer
- The coil of wire and magnet
- 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.
