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.
Answer true/false!
1. Upon leaving the field, a counterclockwise current flows in the loop.
2. When leaving the field the coil experiences a magnetic force to the right.
3. When entering the field the coil experiences a magnetic force to the right.
4. Upon entering the field, a clockwise current flows in the loop.
