We explore the connection between black hole spin and active galactic nucleus (AGN) power by addressing the consequences underlying the assumption in the recent literature that the gap region between accretion disks and black holes is fundamental in producing strong, spin-dependent, horizon-threading magnetic fields. Under the additional assumption that jets and outflows in AGNs are produced by the Blandford–Znajek and Blandford–Payne mechanisms, we show that maximum jet/outflow power is achieved for accretion onto black holes having highly retrograde spin parameters, an energetically excited yet unstable gravitomagnetic configuration.
