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 represented as?

Solution

The reason as magnet move towards the coil, the magnetic flux non linearly.
Also there is a change in polarity of induced emf, when magnet pass through the coil.
