I would like to quantify the EMI on a circuit and I am confused on how to do that. I have two parallel wires that are laying on top of each other. I have tried to calculate the flux linkage and came up with:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\Lambda[/tex] = [l*[tex]\mu[/tex]_{o}*I/(2pi)]*ln((d-a)/a)

where a=radius of each wire, d=distance between the center of the wires, l=length of the wires, I=current on wire 1, and [tex]\mu[/tex]_{o}*=permeability of free space.

I don't understand how this would induce a current on wire 2 though.

I'd really appreciate any help with this issue.

Thanks,

J
