Question
What happens when a magnet is taken close to a circular coil?
- No effect on the circular coil
- No effect of magnetic field
- Induced current will start flowing
- No current will flow in the circuit
Hint:
An induced current flows when a magnet is taken close to a coil.
The correct answer is: Induced current will start flowing
When a magnet is taken close to a circular coil, an induced current will start flowing.
- When a magnet is taken close to the coil, it induces an electromagnetic field.
- The electromagnetic field induces electromagnetic force.
- This will lead to the formation of induced current in the electromagnetic field.
