Shows a long current carrying wire and two rectangular loops moving with of velocity `v`. Find the direction of current in each loop.

Text Solution

Verified by Experts

In loop (i), no emf will be induced because there is no flux change. In loop (ii) emf will be induced because the coil is moving in a region of decreasing magnetic field in inward direction. Therefore, to oppose the decrease in flux in inward direction, current will be inwards. For this, direction of current should be clockwise.
