The figure shows a cross section of an infinite conducting sheet carrying a current per unit x-length of λ; the current emerges perpendicularly out of the page. (a) Use the Biot – Savart law and symmetry to show that for all points P above the sheet and all points Ṕbelow it, the magnetic field is parallel to the sheet and directed as shown. (b) Use Ampere’s law to prove that ? = 1 ?0?2 at all points P and Ṕ.
