    Abstract:
    We discuss the photon motion in the framework of general relativity coupled to non-linear electrodynamics. Photons no longer follow the null-geodesics of the spacetime but rather null-geodesics of associated effective metric. Here we compare structure of circular geodesics and time-delays of neutrinos in Bardeen spacetimes with those of photons in effective geometry. We also discuss construction the Keplerian disks images in the Bardeen spacetimes and compare them with the images of Keplerian disks in RN spacetime.
