HW 9 Phys5405 f05 due 11/17/05 1)Calculate A in the Coulomb gauge at some point a distance ρ from a wire of length L carrying current I in the z direction. A line from the point to the wire divides the wire into lengths L 1 and L 2 . Take the curl of A and show that the B found in class is obtained. 2)JDJ 5-4 (Do not solve any partial diﬀerential equation as we haven’t yet covered the solu-
