Hello Jonathan. Finally i can see the coil you talk about.
I have made an analysis with the rule of the hand to see the current flux and the magnetic field created, and it seems not to create magnetic flux, because the lines of flux that one turn creates seem to be compensed by the return flux lines of the surrounding turns, so the flux density doesn't change, or keeps very low (at least, near the center of the coils, around the external edges, there is magnetic flux not compensed).
So you could put the current you want, the flux density will not change near the center.
What will happen if we change the strength of the field near that coil?
I have done some simulations, and the flux lines of a changing element near the coil doesn't seem to be affected, but sure the coil sees this changes, but i can't say if this variation creates a current or voltage. If it does, the fact that it will not create backEMF (because the current running through the coil will not change magnetic flux state) could be true.
