1. The problem statement, all variables and given/known data Two wires with the same intensity but with opposite directions. The magnetic field of the middle line between the two wires is: a) (X) b) (o) c) Parallel between the two wires d) Null e) Non of the above. 2. Relevant equations N/A 3. The attempt at a solution Knowing that they both colide in the middle since the top wire goes (X) on the bottom and (o) at the top, while the bottom wire does the opposite. I can't figure if it's Parallel or Null. Can someone explain me which one is the right one? I used the right hand rule.
