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, bck into a field free region to the right. The self inductance of the Toop is negligíble. While the loop is entirely in the field, the emf in the loop is zero. Upon entering the field, a clockwise current flows in the loop When leaving the field the coil experiences a magnetic force to the right. When enteringthe field the coil experiences a magnetic force to the left. Tries 0/8 Submit Answer

Explanation / Answer

option a is true because in this case flux does not changes hence there will be no E.M.F

option b is also true because in this case current flows in counterclockwise direction.

option c is also true when the loop leaving the field the direction of current is clockwise direction.

option d is false because while entering the field the field will try to oppse towards the right.
