1. The problem statement, all variables and given/known data I was just wondering, so lets say there are two current carrying wires in the same plane that are perpendicular. One of them is infinite length, the other is a wire segment some distance away from the first one and perpendicular to it. What's the force on the wire segment? 2. Relevant equations 3. The attempt at a solution People have been saying it's zero cuz the magnetic field is parallel to the wire segment, but I don't think that's true. I think that it's still perpendicular so there'll be a force on it. Am I right?
