Chapter 29, Problem 19(choose chapter or problem)
One long wire lies along an x axis and carries a current of 30 A in the positive x direction.A second long wire is perpendicular to the xy plane, passes through the point (0, 4.0 m, 0), and carries a current of 40 A in the positive z direction.What is the magnitude of the resulting magnetic field at the point (0, 2.0 m, 0)?
