Homework Statement
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.

A) Upon entering the field, a clockwise current flows in the loop.
B) While the loop is entirely in the field, the emf in the loop is zero.
C) Upon leaving the field, a clockwise current flows in the loop.
D) When entering the field the coil experiences a magnetic force to the right.
E) When leaving the field the coil experiences a magnetic force to the left.
Homework Equations
k so i assume we use the right hand rule for all of these.
The Attempt at a Solution
The only one that I know for sure to be right is B. Other then that I am a little confused. if you can just give me some hints that would help greatly
