how to define a currnet in a ring from coil in 3d

Please login with a confirmed email address before reporting spam

hi ,
i am trying to define the current (dc-constant) in a shaped as ring coil in 3d .
i have difficulty to do so since i think i need some kind of function to consider the angles (even though the current is constant and uniform )
thank you.

for the time harmonic solver, i use the equation:

Jx = J0*y/sqrt(x^2+y^2)

Its just a geometric relation for the tangent of a circle given some current ensity J0 (similar triangles).
