High energy and very high energy (VHE >10 GeV) γ-rays are expected to be produced from the vicinity of super-massive black holes (SMBH). In the magnetosphere of a spinning black hole acceleration of particles will take place in the field gaps. VHE emission from these particles is feasible via several processes. Systems surrounded by a low photon field will allow the emission to escape. In order to predict the level of emission of these systems, the mass of the central object and the intensity of the magnetic field need to be known. An estimate of the magnetic field is obtained here using the connection between BH magnetosphere and the magnetized accretion disk. Predicted fluxes and energy domain of the corresponding VHE emission are discussed.
