Homework Equations
The Attempt at a Solution
The magnetic field in the bar magnet is directed to the right, but weakening in magnitude because the magnet is being moved far away from the loop. So by Lenz's law, the magnetic field created by the induced current must be to the right. That eliminates B,D, and E.
But I don't understand how a force can be created on the loop. I know that the answer choice is actually C (the loop is attracted towards the magnet) but why should this be the case? Lenz's law is already accounted for, after all.
