Divergence VS Dimensions

I performed different simulations of flat coils to see the magnetic flux density without any error and results look reasonable.
The problem is that when I reduce the size of the flat coil (Diameter=30 [mm] , wire diameter=1 [mm]), and choose a finer mesh, Comsol fails to find a solution:
Failed to find a solution.
Divergence of the linear iterations.
Returned solution is not converged.
I am using Magnetic Fields physic. Should I use a different physic for very small devices?
Is the divergence because of the very small size?
Thanks,
Nima.
