    "abstract": "We review the energy contents formulae of Kerr-Newman black-holes, where\ngravitomagnetic energy term comes to play(Berman, 2006; 2006a; 2004). Then, we\nobtain the angular momenta formulae, which include the gravitomagnetic effect.\nThree theorems can be enunciated: (1) No black-hole has its energy confined to\nits interior; (2) Rotating black-holes do not have confined angular momenta;\n(3) The energy density of a black-hole is not confined to its interior. The\ndifference between our calculation and previous ones by Virbhadra(1990, 1990a,\n1990b), and Aguirregabiria et al.(1996), lies in the fact that we include a\nterm responsible for the self-gravitational energy, while the cited authors\ndiscarded such effect, which appears in the static black hole energy\ncalculation.",
