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 right. The self inductance of the loop is negligible.
The B Field is moving towards the right

Upon leaving the field, a clockwise current flows in the loop. TRUE OR FALSE
When leaving the field the coil experiences a magnetic force to the right. TRUE OR FALSE
When entering the field the coil experiences a magnetic force to the right.TRUE OR FALSE
Upon entering the field, a clockwise current flows in the loop. TRUE OR FALSE

Explanation / Answer

Upon leaving the field the direction of current depends on the direction of field ie if field is into the plane then clockwise ,if field is out of plane then counter clockwise When leaving the field the coil experiences a magnetic force to the right--FALSE When entering the field the coil experiences a magnetic force to the right--FALSE Upon entering the field the direction of current depends on the direction of field ie if field is into the plane then counter clockwise,if field is out of plane then clockwise
