Figure 29-84 shows a cross section of an infinite conducting sheet carrying a current
Chapter 29, Problem 81(choose chapter or problem)
Figure 29-84 shows a cross section of an infinite conducting sheet carrying a current per unit x-length of l; the current emerges perpendicularly out of the page. (a) Use the BiotSavart law and symmetry to show that for all points P above the sheet and all points P below it, the magnetic field is parallel to the sheet and directed as shown. (b) Use Amperes law to prove that at all points P and P . P'xBB Figure 29-84 81.
