Abstract

In this work we study the orbit of light particles around a asymptotically flat, magnetically charged black hole which is coupled to a model of nonlinear form of Maxwell electrodynamics. The matter source is characterized by two parameters, -\beta- and -\gamma-, which determine the behaviour of photon around the corresponding spacetime. We serve the effective potential and analyze its change by varying the charge and the model paramater. Finally, we solve its orbit equation and show how photon moves according to the black hole potential.
