Abstract Magnetic Fields Around Black Holes
... Such enormous powers prompts us to consider highly efficient mechanisms of energy production. The efficiency is characterized by the fraction of accreted rest mass that is radiated, i.e. L = ηṀc2 , where Ṁ is the mass accretion rate onto the black hole. The most efficient mechanism known is matter ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
