Question
A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the right. For each statement select T True, F False. (If the first is T and the rest F, enter TFFFF. ) A) While the loop is entirely in the field, the emf in the loop is zero. B) Upon leaving the field, a clockwise current flows in the loop. C) When leaving the field the coil experiences a magnetic force to the left. D) Upon entering the field, a clockwise current flows in the loop. E) When entering the field the coil experiences a magnetic force to the right.
