Rank in order, from strongest to weakest, the pulling forcesthat must be applied to keep the loop moving at constant speed. 1. F2 = F4 > F1 = F3 2. F3 > F2 = F4 > F1 3. F3 > F4 > F2 > F1 4. F4 > F2 > F1 = F3 5. F4 > F3 > F2 > F1

  10. A conducting loop is halfway into a magnetic field. Suppose the magnetic field begins to increase rapidly in strength. What happens to the loop? 1. The loop is pushed upward, toward the top of the page. 2. The loop is pushed downward, toward the bottom of the page. 3. The loop is pulled to the left, into the magnetic field. 4. The loop is pushed to the right, out of the magnetic field. 5. The tension is the wires increases but the loop does not move.
