The magnet moves as shown. The field of the magnet through the coil is
Answer:
Flux through the loop decreases as the magnet is withdrawn.
There fore to prevent this change(Lenze’s Law) theinduced current flows in such direction that a north pole is induced at the left side of the coil andit attracts the south pole of theretreating bar magnet.
Hence the current as seen from the retreating bar magnet side is counterclockwise
Therefore this time theinduced current flows from right to left in the current meter.
Answer is A) to the left and the primary flux through the coil is decreasing
