10. A conducting wire frame is placed in magnetic field which is directed into the paper. We

increasing at a constant rate. The directions of induced current in wires AB and CD arexx сx

Answered by admin @ 13/08/2021

Answer:

The direction of induced current in wires AB and CD is anticlockwise

B→A and D→C.

Explanation: According to Lenz law an induced emf induces a current whose magnetic field opposes the change in magnetic flux.
