The variation of induced 
with time (t) in a coil, if a short bar magnet is moved along its axis with a constant velocity is best represented as
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As the magnet moves towards the coil, the magnetic flux increases (non-linearly). Also, there is a change in polarity of induced emf when the magnet passes on to the other side of the coil. So, correct variation is shown in .
