1. The problem statement, all variables and given/known data 2b. Suppose the a third wire, carrying another current i0 out of the page, passes through point P. Draw a vector on the diagram to indicate the magnetic force, if any, exerted bon the current in the new wire at P. If the magnitude of the force is zero, indicate that explicitly. Explain your reasoning. 2. Relevant equations N/A 3. The attempt at a solution For problem 2 I drew the currents around all three wires using the right-hand rule and immediatly got confused on how to determine the direction vectors. I want to say it will be straight down since the left wire will cancel out with the right wire thus leaving only the top wire to exert a magnetic force.
