Two long, straight wires, one above the other, are seperated by a distance 2a2a and are parallel to the x−axisx−axis. Let the +y−axis+y−axis be in the plane of the wires in the direction from the lower wire to the upper wire. Each wire carries current II in the +x−direction+x−direction. Find B⃗ B→ - the net magnetic field of the two wires at the following points in the plane of the wires.
