    2. Relevant equations

    I have no idea where to start

    3. The attempt at a solution

    Similarly. If someone could give me some direction to solve this I would really appreciate it.

    We require some indication of effort before giving help. For example, you should at least be able to tell us something about the magnetic fields at the center of the arc produced by the two currents.

    What is the direction of B1 at the center of the arc that is produced by current #1? Similarly, what is the direction of B2 at the center of the arc that is produced by current #2?
