A square loop of side 12 cm with its sides parallel to X and Y axes ismoved with a velocity of 8 cm s–1 in the positive x-direction in anenvironment containing a magnetic field in the positive z-direction.The field is neither uniform in space nor constant in time. It has agradient of 10–3 T cm–1along the negative x-direction (that is it increasesby 10 – 3 T cm–1as one moves in the negative x-direction), and it isdecreasing in time at the rate of 10–3 T s–1. Determine the direction andmagnitude of the induced current in the loop if its resistance is 4.50 mW. |
