Effects of electromagnetic field on the motion of particles in dyonic Reissner- Nordstrom black hole

摘要

This paper explores dynamics of particles in the combined gravitational and electromagnetic fields of the dyonic Reissner-Nordstrom background. We discuss possibilities for the particle escape to infinity at inner most stable circular orbit. We study the stability of orbit through Lyapunov exponent and the effective force on particle. The collision of particles is investigated through the center of mass energy near the horizon of black hole. Finally, we compare our results with the motion of particles around Schwarzschild and Reissner-Nordstrom black hole. We conclude that charge of the black hole has a strong effect on the motion of particles.
