Perihelion Shift and Light Deflection in Magnetically Charged Black Holes

In this paper, we consider the influence of magnetic charge q in nonlinear electrodynamics (NED) on two fundamental tests of general relativity: perihelion precession and gravitational lensing. We analyze a magnetically charged black hole. Using weak-field expansions and perturbation theory, we derive analytical expressions for both phenomena. These findings demonstrate that magnetic charge significantly alters spacetime curvature in exotic black hole solutions, providing distinctive signatures for testing modified gravity theories.
