Scientific paper

We proposed in previous papers that variations in the kinematics of the parsec-scale jet of some active galactic nuclei, as well as their long-term periodic variability at optical wavelengths, are possibly related to the precession of their jet inlets. In this work, we study the feasibility of explaining its physical origin through rigid-body precession of the accretion disc due to the misalignment between the angular momenta of the accretion disc and the Kerr black hole, as well as magnetic torques generated from the interaction between a large-scale magnetic field and the induced electric currents in the disc.
