There are two coils A and B as shown in figure. A current starts flowing in B as shown, when A is moved towards B and stops when A stops moving. The current in A is counter clockwise. B is kept stationary when A moves. We can infer that |

Answer» there is a constant current in the clockwise direction in A. Now induced current in loop B is in counter clockwise which indicates that in loop A also current should be in counter clockwise according to Lenz.s law. (Consider loop A as MAGNET and think about how magnetic field lines of loop A link with loop B). |
