  We study the dynamics and escape of charged particles initially orbiting a
weakly magnetized Kerr black hole after they get kicked in the direction normal
to the orbit. The case of neutral particles is analysed first and the escape
conditions are given analytically. A general analysis of charged particles
innermost stable circular orbits (ISCO)s is performed numerically. We then
study the charged particles three-dimensional motion and give an effective
condition for their escape. We also discuss how the black hole rotation affects
the escape of charged particles and the chaoticness in their dynamics.
