1. The problem statement, all variables and given/known data There are two problems: 1. At the instant the switch is closed determine the direction of the net force exerted by the magnet on the wire segment at the instant that the magnet is in the position shown. Explain. 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 I don't think there is any relevant equations since this is all theoretical actions. 3. The attempt at a solution For problem 1 I didn't know how to go about it so I used Newton's Third Law. In the previous part they wanted me to find the direction of the current through the wire and by using the right-hand rule I found the current to be ccw so the B-field must point toward the magnet. Now using Newton's Third Law I said that since there must be an equal and opposite force then the net force exerted by the magnet must be towards the wire or the opposite direction of the B-field produced by the wire. Is this reasoning correct? I feel like the wire should have a net force to the right allowing it to be repulsed by the B-field. 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. Any help would be great!
