1. The problem statement, all variables and given/known data So basically there are two parallel wires the wire on the left has an increasing current going north. What would be the direction of the current in the wire left of it? 2. Relevant equations Right Hand Rules 3. The attempt at a solution So I'm really not sure how an increasing or decreasing current affects wires around it. But I'm guessing that right next to the left wire the magnetic field lines are going in.
