The variation of induced emf `(E)` with time `(t)` in a coil if a short bar magnet is moved along its axis with a constant velocity is best represent as

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
The ploarity of emf will be opposite in the two cases while the magnet enters the coil and while the magnetic leaves the coil. Only in option (b) polarity is changing .
