How to induce a domain current in a 3D coil?

I'm trying to study electromagnetic forces applied on a set of two coils from each other's current. The biggest barrier to this is that I cannot determine how to apply a current density such that current goes around the coil. I know that you can do Multiturn Coil Domains in 2D geometries and apply current around a coil in that way, but my studies are 3D configurations in nature so I will eventually need to be working in 3D. Is there an easy way to induce a current around a loop in 3D without actually having to model leads in and out of the loop and apply a voltage potential across them, or do I need to write equations for the External Current Density or Surface Current functions to make that work?
I've attached my model as of now. I've tried to look for solutions to my explicit problem in these forums and in the model gallery, but I apologize if I've missed something there or just in COMSOL in general (I'm just starting off).
Cheers and thank you for any help you can offer,
GG
