We study the effects of large‐scale magnetic fields on the dynamics of charged particles near a rotating black hole. We consider a scenario in which the initially neutral particles on geodesic orbits in the equatorial plane become ionized, and hence they are destabilized by the charging process. Fraction of charged particles are then accelerated out of the equatorial plane and then follow jet‐like trajectories with relativistic velocities. We explore nonaxisymmetric systems in which the magnetic field is inclined with respect to the black hole spin. We study the system numerically in order to locate the zones of escaping trajectories and compute the terminal escape velocity. By breaking the axial symmetry, we notice increasing fraction of unbound orbits which allow for acceleration to ultrarelativistic velocities.

弱磁化旋转黑洞周围带电粒子逸出区的近地平线结构：斜磁层的情况

我们研究了大磁场对旋转黑洞附近带电粒子动力学的影响。我们考虑一种情况，赤道面的测地轨道上的初始中性粒子被电离，因此它们在充电过程中不稳定。然后，带电粒子的分数被加速到赤道平面之外，然后以相对论的速度沿着射流状的轨迹运动。我们探索了非轴对称系统，其中磁场相对于黑洞自旋是倾斜的。为了定位逃逸轨迹的区域并计算最终逃逸速度，我们对系统进行了数值研究。通过打破轴向对称性，我们注意到未绑定轨道的分数不断增加，这允许加速至超相对论速度。
