The variation of induced emf E with time t in a coil when a short bar magnet is moved along its axis with constant velocity as shown in below fig. which fig. is best represented as ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
When the magnet enters in the coil with constant velocity at that time induced emf in the coil is negative and its negative value is increses when it completely inside the coil its induced emf is zero. when it comes out from the other and then induced emf increses with positive value and become zero as it moves away.
