Hi,
First, I would model the coil separately. The coil models in COMSOL are made of closed loops. Perhaps it is is sufficient for a first approach to use the two dimensional "single turn" model in the "magnetic fields" interface (activate the "coil group" Box to connect the windings).
As a next step I would calculate the 3dim-model of the coil. This is much more difficult. First you have to model the connectors. Either there are wires that lead to the model boundary or the two wires meet at a gap (Lumped port). A further difficulty is the mesh. If the wires are close together, the mesh will become very fine.
Incidentally, there are some tutorials about coils. To get a targeted help, you have to describe the problem more accurate or attach a model.
Best regards
