Test particle motion in a regular black hole spacetime

We consider the motion of test particles in the regular space-time given by Ayon-Beato and Garcia in Phys. Rev. Lett. 80:5056 (1998), which is a solution to the Einstein equations coupled to a nonlinear electrodynamics. In particular we study the radii of stable circular orbits for black holes as well as for the over extreme case without horizons.
