Abstract: (APS)

We calculate explicitly the system of a spherical shell of radius R, carrying (nearly) arbitrary mass M and charge q, and rotating slowly around an axis through its center. We discuss, mainly graphically in the plane of the model parameters M/R and q/R, the following properties of this system: The dragging of inertial frames which turns over to antidragging in part of the parameter space, the induced magnetic field, the angular momentum, the magnetic moment, and the gyromagnetic ratio. The latter is very near to the value 2 in an overwhelming part of the parameter space, and we argue that this signals a deep connection between general relativity and quantum theory which could be important in the search for quantum gravity.
