Abstract
In this study, we explored the motion of electrically charged test particles in the vicinity of a static, regular Einstein–Bronnikov black hole. The particle equations of motion were established, allowing us to examine key features such as the event horizon, the effective potential, and the radius of the innermost stable circular orbit of the Einstein–Bronnikov black hole. Our analysis reveals that, within specific parameter ranges, the magnetic charge \(q_m\) of the Einstein–Bronnikov black hole can effectively emulate the spin parameter α of a Kerr black hole. These findings offer valuable guidance for investigating the behavior of charged particles and for drawing comparisons between different black hole models.
