Deflection angle of photon from magnetized black hole and effect of nonlinear electrodynamics
Abstract In this paper, we analyze deflection angle of photon from magnetized black hole within non-linear electrodynamics with parameter $$\beta $$ β . In doing so, we find the corresponding optical spacetime metric and then we calculate the Gaussian optical curvature. Using the Gauss–Bonnet theore...

| Summary: | Abstract In this paper, we analyze deflection angle of photon from magnetized black hole within non-linear electrodynamics with parameter $$\beta $$ β . 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–Nordström (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. |
