Distinguishable feature of electric and magnetic charged black holeAcceleration of charged particle in Reissner–Nordström spacetime

Obviously, from the geometrical point of view, it is impossible to distinguish the electrically and magnetically charged Reissner–Nordström black holes. One way of describing the differences between these solutions is to study the dynamical motion of charged test particles in the vicinity of the charged black hole and explore the effects of the charge coupling parameters (σe,σm\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\sigma _e,\sigma _m$$\end{document}) on the instability of the circular orbits. On the other hand, it is also possible to investigate the fundamental frequencies, such as Keplerian, Larmor, and epicyclic frequencies of charged particles orbiting around a charged black hole. Lastly, we investigate the synchrotron radiation by charged particles accelerated by charged black hole and estimate the intensity of relativistic radiating charged particles. Finally, we comment on the possible utilization of our findings for the relativistic jets and magneto-hydrodynamical outflows.
