In this article, we study the dynamics of neutral as well as charged particle in the presence of magnetic field around Reissner-Nordström black hole surrounded by quintessence by taking into account Noether symmetries and conservation laws in the corresponding spacetime. Using these conservation laws, we explore the effect of angular momentum, quintessence parameter, and magnetic field graphically on the dynamics of neutral/charged particles in the context of the effective potential, effective force, and escape velocity. Additionally, we investigate the orbit stability of the said spacetime with the help of the Lyapunov exponent.

典型的Reissner-Nordström黑洞周围的粒子动力学

在本文中，我们通过考虑相应时空中的Noether对称性和守恒律，研究了存在于精粹包围的Reissner-Nordström黑洞周围磁场存在下的中性粒子以及带电粒子的动力学。使用这些守恒定律，我们在有效势，有效力和逃逸速度的背景下，以图形方式探索了角动量，典型参数和磁场对中性/带电粒子动力学的影响。另外，我们借助李雅普诺夫指数研究了所述时空的轨道稳定性。
