## Homework Statement

Suppose you have three closed loops (ring-like) Each one has current going through it. They are set parallel to each other and the same distance away from each from each other. Suppose also the current through the one in the middle loop and the one on the right loop move counterclockwise if we looked at the loops from the right side. However, the left lopp's current is opposite to the other rings (clockwise as seen from the right side too) The question is what is going to happen to the previous configuration? Is any of the loops going to rotate if we supposed that their centers are stationary?

## Homework Equations

I know F=IVxB

## The Attempt at a Solution

I tried applying the formula, but the force direction I get is always perpendicular to the rings (no tangential force) which means no rotation will occur but the answer says that the left ring (the one with opposite current direction) will rotate?!
