Hello.

I'm floundering.

What is the right way to formulate a problem of calculating the current density distribution across the wire's cross-setion, taking into account eddy currents? If the Maxwell's equations are not the way to go, what is? What should be the boundary conditions or any other restrictions placed on the solution?

Thank you in advance.

Thanks big time. That's not altogether what I meant though. I know quite a few things about skin effect, but I have a rather specific problem in mind.

I have two wires in close proximity carrying currents at the same frequency. I need to visualise the current density distribution in each of them. It is quite obvious that I have to do it numerically but I cannot really put my finger on how to pose the problem correctly.

I would really appreciate your help, it is important.

Thank you.
