Force-free Magnetosphere of a Kerr Black Hole and Energy Extraction

Recent results on the electrodynamics of Black Holes will be discussed using the 3+1 (space and global time) formalism. This formalism has permitted the construction of an exact class of solutions to the Blandford-Znajek mechanism. Physical properties of the exact solution are analyzed following which the nature of jet formation and energy extraction from Kerr Black Holes will be presented.
