In this article, we study the particle dynamics around a static andspherically symmetric Bardeen-Kiselev black hole (BK BH) which is a solution ofthe Einstein-non-linear Maxwell field equations along with a quintessentialfield. We discuss its essential geometrical properties such as scalarinvariants and size of innermost stable circular orbits. Dynamics of testparticles around the BH is also studied. Moreover, we also computed thefundamental frequencies of a test particle orbiting the BH in a slightlyperturbed orbit. Further, the degeneracy relations between the spin of rotatingKerr BH and magnetic charge of the BK BH at the values of the quintessentialparameter $\omega_q=-1/3$ and in terms of the same values of innermost stablecircular orbits (ISCOs) radius, energy efficiency, twin-peaks quasiperiodicoscillations (QPOs) frequencies and impact parameter for photon are alsodiscussed in detail. Finally, we have investigated the relationship between theshadow radius and the real part of the quasinormal mode (QNM) frequency.
