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. The self inductance of the loop is negligible. True or False answers When entering the field the coil experiences a magnetic force to the right. When leaving the field the coil experiences a magnetic force to the left. Upon leaving the field, a counterclockwise current flows in the loop. Upon entering the field, a counterclockwise current flows in the loop.
