Question

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 J_w represents the current per unit width along the plane, measured in amperes per meter.

Diagram of an infinite plane with current density Jw flowing into the plane, illustrating Ampere's Law.
