Abstract

We discuss dynamical properties of generally non-Kepierian equatorial circular orbits and zero-angular-momentum spherical polar orbits around Kerr-Newman black holes. By considering charged test particles, the thrust is represented by the Lorentz force. Below photon orbits, the acceleration of a given type of orbits depends on their orbital angular velocity in a counter-intuitive manner. We interpret this result in terms of suitably defined forces of classical type.
