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. (True or false)
Upon entering the field, a counterclockwise current flows in the loop.
While the loop is entirely in the field, the emf in the loop is zero.
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 left.

by using right hand thunmb rule
by using len's law also we need to find the direction of current
