Questions  

The graph shows the variation in magnetic flux ϕ(t) with time through a coil. Which of the statements given below is not correct?

a
There is a change in the direction as well as magnitude of the induced emf between B and D
b
The magnitude of the induced emf is maximum between B and C
c
There is a change in the direction as well as magnitude of induced emf between A and C
d
The induced emf is zero at B

detailed solution

Correct option is D

At B , flux is maximum, so from |ε|=dϕdt at B, |ε|≠0
