A conducting square frame of side and a long straight wire carrying current are located in the same plane as shown in the figure. The frame moves to the right with a constant velocity The emf induced in the frame will be proportional to

To solve this problem, we need to determine the emf induced in the square frame as it moves with velocity near a long straight wire carrying current The magnetic field due to a long straight wire at a distance is given by:
