The catch is that our coil has a current running through it, while our outer tube does not except that due to Eddy currents.

For two Coaxial coils, the mutual Inductance formula I found was:

M = μ*n1*n2/(π*(r1)^2) where n = N/l

While for the Coaxial cable it was:

L/l = μ/(2π)*ln(r1/r2)

To clarify, we have a coil with a current inside of a conducting tube. I would like to know the Inductance here. Can anybody point me in the right direction to solve this in our set up?

Thanks!
