Abstract

A new magnetically charged Kiselev black hole solution is used to study the null geodesics in this spacetime. We derive the equations of motion for the null geodesics and analyze their properties, including the gravitational lensing effect. The 3D and equatorial plane orbits are discussed, with particular attention given to the effect of quintessence. The deviations from the Ernst black hole provide insights into the potential observational consequences of dark energy in strong gravitational fields.
