Problem

Two long parallel wires lie in the x-y plane, and each carry 5.0A currents in opposite directions. Wire 1 lies along the y=3.0cm line and carries a current in the negative x direction; wire 2 lies along the y=0 line and carries a current in the positive x direction. What is the direction of the magnetic field at the point (0cm, 0cm, 1.5cm)?
