The paper investigates the combined effects of non-linear electrodynamics (NED) and dark matter (DM) on a magnetically charged black hole (BH) within a Hernquist DM halo. The study focuses on how magnetic charge and halo parameters influence BH observables, particularly event horizon position, critical impact parameter, and strong gravitational lensing (GL) phenomena. A key finding is the potential for charge and halo parameters to nullify each other's effects, making the BH indistinguishable from a Schwarzschild BH in terms of certain observables. The paper also uses observational data from super-massive BHs (SMBHs) to constrain the model parameters.
