Several times in my physics lessons, I have encountered a problem similar to the following:
This coil has been moving in such a way as to decrease flux. After the switch is closed, will the induced voltage cause electrons in the coil to move clockwise or counterclockwise?
and I always seem to have the wrong answer for this type of problem. I understand that the Xs mean that the magnetic field is pointed into the drawing, rather than out of it, but I'm not sure how to solve for the right direction.
