Pay attention to the enormous value of the magnetic intensity in the geometric center of both the electron and the proton !!!
The proton and also the electron structure are not rings at all. The basic orbit is the Clifford torus. The topology of the fields is very complex as e.g. the proton magnetic moment is not formed by the internal binding charge is the charge that binds the 3/5 wave structures and also forms the external potential.
But this does not significantly change the magnitudes for the B field, that for nuclear interactions is around 1014T.
