Unformatted text preview: Ampereâ€™s Law I B Â· d l = Âµ I We must generalize this equation. â€“ p. Paths and surfaces I Two surfaces border on the closed path. The same current flows through both surfaces. â€“ p. Paths and surfaces II Two surfaces border on the closed path, and different currents flow through them. â€“ p. 1 Ampereâ€™s Law â€“ final form I B Â· d l = Âµ I + Âµ Â± I âˆ‚ E âˆ‚t Â· d A â€“ p. 1 Ampereâ€™s Law inside C Apply Ampereâ€™s Law to a circle of radius r . The time dependent E field (displacement current) causes a B field. â€“ p. 1 Maxwellâ€™s equations I E Â· d A = Q Â± I B Â· d A = 0 I E Â· d l =I âˆ‚ B âˆ‚t Â· d A I B Â· d l = Âµ I + Âµ Â± I âˆ‚ E âˆ‚t Â· d A â€“ p. 1...
