Question
What will happen when a magnet is taken towards a circular coil?
- No current will flow in the circuit
- Induced current will start flowing
- No effect of magnetic field
- No effect on the circular coil
Hint:
When a magnet is taken towards the coil, a current is induced in the coil that will lead to an increased current flow.
The correct answer is: Induced current will start flowing
When a magnet is taken towards a circular coil, an induced current will start flowing.
- The circular coil has a more concentrated magnetic field in the center.
- When a magnet is taken closer to the coil, it will produce an electromotive force (EMF) due to electromagnetic induction.
- Due to the phenomena of electromagnetic induction, when a magnet is moved toward the coil, a current is induced in the coil.
- Electromotive force (EMF), which in turn produces the current in the coil, is induced as a result of the relative movement between the magnet and coil.
