Renoir 80730-440 Curitiba PR Brazil eMail: [email protected] Abstract New formulae are obtained for the energy of K.N. b.h.’s that point out a gravitomagnetic energy effect. The results are valid for slowly or rapidly rotating black-holes. The expression of the energy density of Kerr-Newman back-holes in the slow rotation case, is obtained afterwards, and shown to be essentially positive. ENERGY OF KERR-NEWMAN BLACK-HOLES AND GRAVITOMAGNETISM Marcelo Samuel Berman 2 There are pretty standard pseudotensor calculations presented in the book by Adler et al..The most general black hole is characterized by mass M, electric charge Q and rotational parameter ”a” and is given by Kerr-Newman’s metric, where in quasi-Cartesian form, is given by: ds = dt − dx − dy − dz − 2 [
