Force due to a magnetic field conceptual question

1. The problem statement, all variables and given/known data
A metal loop is dropped between the poles of a magnet. The pole on the left is a North pole, while the pole on the right is a South pole. Assume the magnetic field is uniform between these poles.

Does the loop feel a force? If so, what direction is that force in?

2. Relevant equations

3. The attempt at a solution
The magnetic field lines point from left to right (eg. North to South). The loop is entering the field, so the magnetic flux through it is increasing towards the right.

To oppose this change in magnetic flux, there is an induced current in the loop that goes in the direction of my fingers when I point my thumb towards the left.

The force felt by the loop, overall, is zero (because on one side of the loop, the force points in one direction. On the opposite side of the loop, the force points in the opposite direction. This means they cancel and the net force is zero).

Can anyone tell me if I'm completely off base here, or if I'm on the right track?
