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. The self inductance of the loop is negligible. When entering the field the coil experiences a magnetic force to the right. While the loop is entirely in the field, the emf in the loop is zero. Upon entering the field, a clockwise current flows in the loop. When leaving the field the coil experiences a magnetic force to the left.
