MECHANISMS OF ENERGY EXTRACTING AROUND THE BLACK HOLES

The purpose of article is to investigate an electromagnetic field and effective potential of charged and test particles in the vicinity of axial-symmetric black holes immersed in an external magnetic field and energy extraction around of axial-symmetric black holes in the Kerr-Taub-NUT spectime by using Penrose process. So far, it has been very essential to reveal the roperties of jets coming from compact objects (radiation of quasars). Recently, a charged particle motion and a process of energy extraction around Kerr and Kerr-Newman black holes has been imnvestigated by several authors with the help of penrose process. In our dissertation, we apply Penrose prosess to the Kerr-Taub-NUT spacetime and analyse results
