A rectangular loop of wire moves with a E constant speed v throughout this problem. It is initially in a field-free region. It passes through the gray region which has a constant uniform magnetic field (field points perpen- dicularly out of the page) and then exits to a field-free region. BO B 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. D 3.A 4. C 5
