TL;DR

This paper investigates how nonlinear electrodynamics influences the deflection angle of photons around magnetized black holes, revealing modifications to gravitational lensing effects in weak field regimes.

Contribution

It introduces a new analysis of photon deflection in nonlinear electrodynamics, extending classical results to include effects of the parameter β and magnetic charge.

Findings

Nonlinear electrodynamics alters photon deflection angles.

Results reduce to Maxwell and Reissner-Nordström cases when parameters are simplified.

Graphical analysis shows dependence of deflection on charge, impact parameter, and nonlinear parameter.

Abstract

In this paper, we analyze deflection angle of photon from magnetized black hole within non-linear electrodynamics with parameter $\beta$. In doing so, we find the corresponding optical spacetime metric and then we calculate the Gaussian optical curvature. Using the Gauss-Bonnet theorem, we obtain the deflection angle of photon from magnetized black hole in weak field limits and show the effect of non-linear electrodynamics on weak gravitational lensing. We also analyzed that our results reduces into Maxwell's electrodynamics and Reissner-Nordstr\"{o}m (RN) solution with the reduction of parameters. Moreover, we also investigate the graphical behavior of deflection angle w.r.t correction parameter, black hole charge and impact parameter.
