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. prob24_loop3.gif True False When leaving the field the coil experiences a magnetic force to the left. True False Upon entering the field, a clockwise current flows in the loop. True False When entering the field the coil experiences a magnetic force to the right. True False Upon leaving the field, a clockwise current flows in the loop.

Explanation / Answer

True---------When leaving the field the coil experiences a magnetic force to the left.

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

-False -----------When entering the field the coil experiences a magnetic force to the right.

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