One of the notable modifications of General Relativity (GR) is the Rastall gravity. We have studied the quasinormal modes of black holes in Rastall gravity in presence of non-linear electrodynamic sources. Here the impacts of cosmological field, dust field, phantom field, quintessence field and radiation field on the quasinormal modes in presence of electrodynamic sources have been investigated. Apart from this, we have also checked the dependency of quasinormal modes with the Rastall parameter $\lambda$, black hole structural constant $N_s$ and charge of the black hole $Q$. The study shows that the quasinormal modes corresponding to the black hole with non-linear electrodynamic sources show significant deviations from a general charged black hole in Rastall gravity under certain conditions. Further, the behaviour of black holes and hence the quasinormal modes depend on the type of surrounding field considered.

广义相对论 (GR) 的显着修改之一是拉斯托尔引力。我们研究了存在非线性电动力源的拉斯托尔引力中黑洞的准正规模式。这里研究了宇宙学场、尘埃场、幻影场、精华场和辐射场对存在电动源的准正规模式的影响。除此之外，我们还使用 Rastall 参数检查了拟正规模态的依赖性$\lambda$, 黑洞结构常数 $N_{秒}$ 和黑洞的电荷 $问$. 研究表明，与具有非线性电动力源的黑洞对应的准正规模式在一定条件下与拉斯托尔引力中的一般带电黑洞存在显着偏差。此外，黑洞的行为以及准正规模式取决于所考虑的周围场的类型。
