Hello,
First of all I want to say that I am not an EE, I am an ME but I am working for an EE laboratory on campus and am trying to get a force from and electrical circuit on a project here.
I am using the following equations:
F = 1/2*L'*I^2 (where L' = H/m)
and
F = u_0*I_1*I_2*d/(2*pi*r) (where d = length of conductors and r = their separation distance)
I am trying to get the forces acting upon two parallel conductors with opposite current direction. With my hand calculations and simulation in LTspice I am getting a number greater by a factor of 5 with the second equation than with the first.
I have reason to believe the first equation is not valid for what I want but I want to get a second or third opinion.
Thank you ahead of time!
