When a bar magnet is brought closer to a coil, emf generated in the coil does not depend on ______

A

no. of turns

B

velocity of magnet

C

strength of magnetic field of magnet

D

resistance of coil

Text Solution

Verified by Experts

The correct Answer is:
D
Here, emf generated in the coil depends on no. of turns in the coil and rate of change of magnetic flux with one turn (which depends on velocity of magnet and strength of magnetic field of a magnet).
Resistance is always offered to the flow of current, after it is produced.
Thus, emf generated in the coil does not depend on its resistance.
