1. The problem statement, all variables and given/known data I'm trying to find the direction of the current given certain situations, but do not know how to apply Lenz's Law. Attached a image below- 2. The attempt at a solution So I figured out how each situation affects the induced current, and that the magnetic field is to the left. For a), the closing of the switch causes an increased magnetic field. If that's the case, shouldn't the current at resistor R flow to the right? The answer is left.
