Two large, flat current-carrying sheets are placed parallel to each other, one sheet above the other. The upper sheet carries a current density of \(2.0 \mathrm{~A} / \mathrm{m}\) to the left, and the lower sheet carries a current density of \(5.0 \mathrm{~A} / \mathrm{m}\) to the right. Calculate the magnitude of the magnetic field \((a)\) between the sheets, \((b)\) above the upper sheet, and \((c)\) below the lower sheet. \((d)\) Draw a diagram showing the direction of the magnetic field in each of these regions.
