The internal EM structure of the source in the Kerr (1963) and Newman et al. (1965) solution of the Einstein-Maxwell equations for a spinning charged mass is investigated theoretically. The derivation of the governing equations is given in detail, and the source structure is briefly characterized. It is shown that the EM field originates in a system of electric currents and surface charges distributed over a disk of radius equal to the length parameter (a), so that only a and the electric charge (and not the mass and the angular momentum) enter the analysis; a gyromagnetic ratio of 2 is found for both the dipole component and the total magnetic moment. The implications of the results for a proposed Kerr-Newman model of the atomic nucleus (Pekeris, 1987) and for theoretical models of rotating charged stars or black holes are indicated.
