One long wire lies along an x axis and carries a current of 50 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 6.6 m, 0), and carries a current of 68 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 1.2 m, 0)?
