Abstract Using the BPS Lagrangian method, we obtain a distinct set of Bogomolny equations for the Cho–Maison monopoles from the bosonic sector of a regularized electroweak theory. In the limit of $$n\rightarrow \infty $$ n → ∞ of the permittivi

Abstract We study nonsingular black holes viewed from the point of view of Ayon-Beato–Garcia (ABG) nonlinear electrodynamics (NLED) and present a complete study of their corresponding strong gravitational lensing. The NLED modifies the the photon
