Correct answer: (a)
Explanation:
As the magnet is approaching the loop, magnetic flux increases and the rate of increment of flux also increases so emf increases with time.
At this moment emf is maximum
Magnet is in the middle of the coil, at this moment emf is equal to zero.
Now, again flux start changing however polarity of emf get reverse
Hence, the graph will be
