Problem

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