A small bar magnet is being slowly inserted with constant velocity inside a solenoid as shown in figure. Which graph best represents the relationship between emf induced with time

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Intentially, `(phi_B)` increase as magnet approaches the solenoid
`:. (epsilon)=-ve`and increasing in magnitude. When magnet is moving inside the solenoid, increse in `(phi_B)` slow down and finally `(phi_B)` starts decreasing
`:. Emf is positive and increasing.`
Only graph (c) shows these characteristic.
