2.) You have a rectangular coil of wire consisting of a single loop. The long sides are each 20 cm long and the short sides are each 10 cm long (20x10 cm). A magnetic field of 3.5 T points through the loop as shown at right. (a) With the field remaining constant, suppose you now stretch the coil so that the dimensions are 25x10 cm. The stretching takes 2.0 seconds. What is the voltage on the loop during that time? What direction would the current flow from your perspective during this process (clockwise or counterclockwise)? X X X X X X X X X X X X X X X X X X X X X X X X X (b) Suppose that instead of stretching the 20x10 cm coil you had decided to squeeze it into a perfect square 10x10 cm. Again, the process takes 2.0 seconds. What is the emf on the coil and the direction of the current in this case?
