The Blandford–Znajek Mechanism

The leading explanation for how relativistic jets are powered: magnetic field lines threading a spinning black hole extract its rotational energy and fling plasma outward. Proposed by Roger Blandford and Roman Znajek in 1977, it lets a black hole act as a cosmic engine, converting spin into the enormous power of a jet.
