The structural properties of geodesic currents in an ambient Kerr background are studied from an analytical point of view. The geodesics in this congruence may correspond to charged particles that carry energy and angular momentum from the black hole through the Blandford-Znajek mechanism. It is shown that the resulting magnetosphere naturally satisfies the Znajek regularity condition. Particular attention is paid here to the energy extracted by matter currents rather than by electromagnetic Poynting fluxes. This analytic study is motivated by the mathematical structure behind the Blandford-Znajek process, and may only have limited applications to the astrophysics of supermassive black holes.
