A conducting wire frame is placed is placed in a magnetic field which is directed into the paper. The magnetic field is increasing at a costant rae. The directions of induced currents in wires AB and CD are

(a) B to A and D to C

(b) A to B and C to D

( c) A to B and D to C

(d) B to A and C to D

Text Solution

Verified by Experts

The correct Answer is:

(a) Magnetic field in `ox` direction is increasing. Therefore, induced current will produce magnetic field in `o.` direction. Thus, current in both the loops should be anticlockwise. But as the side will be more compared to the left side loop.
Therefore, net current in the complete loop will be in a direction shown below:
