(Answered) : Square Loop Wire Small Resistance Moved Constant Speed Field Free Region Region Uniform B Q28893752

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. Upon entering the field, a counterclockwise current flows in the loop. while the loop is entirely in the field, the emf in the loop is zero. When leaving the field the coil experiences a magnetic force to the left When entering the field the coil experiences a magnetic force to the left.
