true and false,  Loop of Wire in a Field ?

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.

answer true or false :

------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 right.

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

------While the loop is entirely in the field, the emf in the loop is zero.
