29. Sources of Magnetic Field / Ampere's Law (Calculus) / Problem 10
Determine the magnitude of the magnetic field at a distance z above an infinitely large horizontal plane. The current is flowing into the plane of the figure (positive y-direction). Hint: The linear current density Jw represents the current per unit width along the plane, measured in amperes per meter.
