  Spinning black holes create electromagnetic storms when immersed in ambient
magnetic fields, illuminating the otherwise epically dark terrain. In an
electromagnetic extension of the Penrose process, tremendous energy can be
extracted, boosting the energy of radiating particles far more efficiently than
the mechanical Penrose process. We locate the regions from which energy can be
mined and demonstrate explicitly that they are no longer restricted to the
ergosphere. We also show that there can be toroidal regions that trap negative
energy particles in orbit around the black hole. We find that the effective
charge coupling between the black hole and the super-radiant particles
decreases as energy is extracted, much like the spin of a black hole decreases
in the mechanical analogue. While the effective coupling decreases, the actual
charge of the black hole increases in magnitude reaching the
energetically-favored Wald value, at which point energy extraction is impeded.
We demonstrate the array of orbits for products from the electromagnetic
Penrose process.
