Unformatted text preview: ECE 329 Homework 6 Due: July 9, 2009, 5PM 1. An infinite current sheet with a uniform current density J s = J s ˆ z A m produces magnetostatic fields B with μ o J s 2 magnitude on both sides of the sheet and with opposing directions in consistency with the right-hand-rule and the Biot-Savart law. Determine the magnetic field intensity H = B μ o at origin O in the following diagrams due to a pair of current sheets with specified J s vectors. Sheet 1 Sheet 2 O J s = 2ˆ z A m (i) x z Sheet 1 Sheet 2 O (ii) x z J s = 2ˆ z A m J s = 2ˆ z A m J s =- 2ˆ z A m 2. Consider an infinite slab (extending in x and y directions) of a finite width W = 2 m described by | z | < W/ 2 . The slab is electrically neutral but it conducts a uniform current density of J = 2ˆ y A/m 2 (meaning that it contains equal densities of positive and negative charge carriers moving in opposite directions parallel to ˆ y ). Outside the slab, that is for z > W/ 2 and z <- W/ 2 , the charge and current densities are zero.densities are zero....
