Homework Help: Infinite plates, with current running through

  1. Mar 6, 2012 #1
    1. The problem statement, all variables and given/known data
    Two infinite sheets of current flow parallel to the y-z plane. The left-hand sheet, which intersects the x-axis at x = 0, consists of an infinite array of wires parallel to the z-axis with a density n = 960 wires/m and a current per wire of IL = 0.15 A in the +z direction. The right-hand sheet, which intersects the x-axis at x = a = 12 cm, is identical to the left-hand sheet, except that it has a current per wire of IR = 0.15 A in the -z direction.

    (a) Calculate the y-components of the net magnetic field in the following places: x1 = -15 cm,

    2. Relevant equations

    B for a wire = u*I/(2*PI*R)

    3. The attempt at a solution

    R = sqrt(h+.15)

    so the y component of B for any wire is


    where theta = arctan(h/.15)

    so, two times the integral from zero to infiniti of B wrt h should give me the right answer
    it does not >_<
