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.
