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 left. The self inductance of the loop is negligible.

When entering the field the coil experiences a magnetic force to the left.
When leaving the field the coil experiences a magnetic force to the right.

Upon entering the field, a clockwise current flows in the loop.
Upon leaving the field, a clockwise current flows in the loop.

TRUE OR  FLASE
