Blandford-Znajek Mechanism

(Blandford-Znajek Process)
(extraction of black-hole rotational energy by magnetized accretion disk)

The Blandford-Znajek Mechanism (or Blandford-Znajek Process) is a means by which a magnetized Accretion Disk can extract rotational energy from a spinning Black Hole. The theory was developed in 1977 by Roger Blandford and Roman Znajek. It is a possible mechanism by which Quasars are powered.
