## Homework Statement

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,

## Homework Equations

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

## The Attempt at a Solution

R = sqrt(h+.15)

so the y component of B for any wire is

sin(theta)*u*I/(2*PI*R)

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 >_<
