Two long parallel wires lie in the x-y plane, and each carry 5.0 A currents 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 = 0y = 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)?
