The motion and acceleration of an electrically charged and magnetized particle around a cylindrical black hole in the presence of an external asymptotically uniform magnetic field parallel to the z-axis are investigated. We look at circular orbits around a central object and study the dependence of the most internal stable circular orbits (ISCO) on the so-called magnetic coupling parameters, which are responsible for the interaction between the external magnetic field and magnetized and charged particles. It is shown that the ISCO radius decreases with increasing magnetized interaction parameter. Therefore, we also studied collisions of magnetized particles around a cylindrical black hole immersed in an external magnetic field, and showed that the magnetic field can act as a particle accelerator near nonrotating cylindrical black holes.

浸入外磁场的圆柱形黑洞周围带电和磁化粒子的动力学

在平行于黑洞的外部渐近均匀磁场存在下，带电和磁化粒子围绕圆柱形黑洞的运动和加速z轴进行研究。我们观察围绕中心物体的圆形轨道，并研究最内部稳定圆形轨道 (ISCO) 对所谓的磁耦合参数的依赖性，这些参数负责外部磁场与磁化和带电粒子之间的相互作用。结果表明，ISCO 半径随着磁化相互作用参数的增加而减小。因此，我们还研究了浸入外部磁场的圆柱形黑洞周围磁化粒子的碰撞，并表明磁场可以在非旋转圆柱形黑洞附近充当粒子加速器。
