A rectangular loop of wire moves with a constant speed v throughout this problem. It D is initially in a field-free region. It passes through the gray region which has a constant uniform magnetic field (field points perpen- 1 . dicularly out of the page) and then exits to a field-free region. BO O Which of the five graphs best describes the induced current i in the loop as a function of 2. time t? Take a clockwise current around the loop to be a positive current, i > 0. E 3 O 4. B 5
