Unformatted text preview: ECE 329 Homework 6 Due: October 6, 2009, 5 PM 1. An infinite current sheet with uniform current density J s produces a magnetostatic field B with magnitude μ J s 2 Wb/m 2 in free space and oppositely directed on either side of the sheet in accordance with the right-hand rule and the Biot-Savart Law. Determine the magnetic field intensity H ≡ B /μ A/m at the origin for the following current sheet configurations: a) A pair of current sheets in the x = 1 and x =- 1 planes with equal current densities J s = 2ˆ z A/m. b) A pair of current sheets in the x = 1 and x =- 1 planes with equal but oppositely directed current densities: J s ( x = 1) = 2ˆ z A/m and J s ( x =- 1) =- 2ˆ z A/m. c) A pair of current sheets in the z = 1 and z =- 1 planes with equal current densities J s =- 2ˆ x A/m. 2. Consider an infinite slab (extending in the 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...
