A bar magnet is moved in the direction indicated by the arrow between two coils PQ and CD. Predict the directions of induced current in each coil.

Text Solution

Verified by Experts

As per Lenz's law, a S-pole is induced at the C-side of the coil CD. So the induced current in CD is such that it is clockwise when seen from the position of NS. Similarly, another S-pole is induced at the Q-side of PQ. So, the induced current in PQ is clockwise when seen from the position of NS.
