  Dynamics of charged particles in the vicinity of a rotating black hole
embedded in the external large-scale magnetic field is numerically
investigated. In particular, we consider a non-axisymmetric model in which the
asymptotically uniform magnetic field is inclined with respect to the axis of
rotation. We study the effect of inclination onto the prevailing dynamic regime
of particle motion, i.e. we ask whether the inclined field allows regular
trajectories or if instead, the deterministic chaos dominates the motion. In
this contribution we further discuss the role of initial condition,
particularly, the initial azimuthal angle. To characterize the measure of
chaoticness we compute maximal Lyapunov exponents and employ the method of
Recurrence Quantification Analysis.
