## Homework Statement

Two infinitely long filaments are placed parallel to the x-axis as shown in Figure 1.

a)Find H at the origin

b)Find H at (-1,2,2)

## Homework Equations

∫Hdl=Ienclosed

H=H1+H2

## The Attempt at a Solution

Well following the equation above I get Hl= Ienc then H1=Ienc/(2piRy) and H2=Ienc/(2piRz) then Ry=(0,0,0)-(0,4,0)=(0,-4,0) then length of Ry=4 and Rz=(0,0,0)-(0,0,4)=(0,0,-4) then Rz=4 thus H1=Ienc/(8pi) and H2=Ienc/(8pi) then H=H1+H2=10/(8pi)+10/(8pi)=20/(8pi)=.795 A/m that is for part a) I only listed this as I used the same method for part b) just with (-1,2,2) instead of (0,0,0)
