    Abstract:
    Being inspired by existence of non-equatorial circular (halo) stable
    orbits of charged particles in composite of gravitational, dipole
    magnetic and co-rotational electric fields near some planets, we find
    possible existence of these orbits in strong gravitational fields
    described by the Kerr-Newman geometry. By using the general relativistic
    inertial forces formalism combined with the effective potential
    approach, we show that the stable halo orbits do exist there. But it
    seems that they are out of the astrophysical importance, being hidden
    under the inner black-hole horizon, or appearing in the naked
    singularity spacetimes.
