Three long parallel wires are located in the x-y plane. The wire in the middle, located along the y-axis at x=0 carries a current of 20.0 amps going up the positive y-axis. The two outside wires each carry a current of 10.0 amps going down they-axis, and they are each a distance of 0.200 m from the center wire. What is the magnitude and direction of the resulting magnetic field these three wires produce at the point (.3,0)
