## Main Question or Discussion Point

Hi,

The gyromagnetic ratio is the ratio of the magnetic dipole moment to the angular momentum.

I really don't get how the fact that the gyromagnetic ratio of a rotating circular loop of mass M and charge Q is g = Q/2M implies that the gyromagnetic ratio of a uniform rotating spere is also g = Q/2M!
