We propose a new model for the disk-jet connection in black hole x-raytransients and active galactic nuclei. In our model, the inner part of theaccretion disk around the central black hole switches between two states. Inone state, the accretion energy is dissipated locally (some within the disk,some within a corona) to produce the observed disk luminosity. In the secondstate, the accretion energy is deposited into the bulk flow of a relativisticjet. We associate the transition between the two states with the generation ofa global, poloidal magnetic field. We show that this model can explain theobserved behavior of black hole accretors.Comment: 12 pages, no figure
