SQUARE LOOP TRUE FALSE?

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.

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

 Upon leaving the field, a counterclockwise current flows in the loop.

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

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

i think the answer is

False

TrueTrueTruebut it's obviously wrong, any help please?

    1) False, as the induction is resistive and always resist the flux change.

    2) True, apply right hand rule

    3) True, as the induction is resistive and always resist the flux change.

    4) False, apply right hand rule
