Exercise 15

The square loop in Figure P20.62 is made of wires with a total series resistance of 10.0 . It is placed in a uniform 0.100-T magnetic field directed perpendicular into the plane of the paper. The loop, which is hinged at each corner, is pulled as shown until the separation between points A and B is 3.00 m. If this process takes 0.100 s, what is the average current generated in the loop What is the direction of the current
