Question
One of the conditions for the phenomenon of electromagnetic induction is that there must be a relative motion between:
- The galvanometer and the magnet
- The coil of wire and the galvanometer
- The coil of wire and the magnet
- The magnet and the galvanometer
Hint:
For the phenomenon of electromagnetic induction to happen, there must be a relative motion between the coil of the wire and the magnet.
The correct answer is: The coil of wire and the magnet
For the phenomenon of electromagnetic induction, there must be a relative motion between the coil of the wire and the magnet.
- The electromagnetic field is formed when a magnet is moved towards a coil of wire.
- A relative motion is created between the coil of the wire and the magnet.
- This relative motion creates an electromagnetic induction.
- Whenever there is a change in the magnetic flux linked with the coil, emf is induced in the coil. This is the phenomenon of electromagnetic induction.
