The magnet in fig. rotates as shown on a pivot through its centre. At the instant shown, what are the directions of the induced currents

Text Solution
Verified by ExpertsThe correct answer is:
A
N pole moves closer to coil CD and S pole moves closer to coil AB on rotation of magnet.
According to Lenz's law, N pole should develop at the end corresponding to C.
∴ Induced current flows from C to D
Also S pole should develop at the end corresponding to B.
∴ Induced current flows from A to B
