1. The problem statement, all variables and given/known data There is a magnetic feild directed inside/ towards the screen. There is also a single rectangular coil parallel to the screen where one of the sides are movable. The magnetc feild increases, what happens to this movable side of the coil. This is my description of the problem, the original was displayed diagrammatically so please ask me to clarify if needed. 2. Relevant equations Lenz's law 3. The attempt at a solution The induced emf in the coil would be anti-clockwise. In order to oppose this change an emf will be induced in the coil. I dont know why the side of the coil should move at all but the answer is that it moves to the right. Can anyone explain to me why?
