    Abstract:
    Results of our recent studies suggest a possibility of existence of halo
    (off-equatorial) electrically charged toroidal structures (thick discs)
    and polar caps circling in axially symmetric backgrounds of central
    objects (compact stars, black holes, etc.) endowed with electromagnetic
    fields. Along with the existence of the halo structures we have also
    found equatorial tori with cusps enabling outflows of matter from the
    torus, without the presence of strong gravity, i.e., also in the
    Newtonian regime. These phenomena represent qualitatively new
    consequence of the interplay between gravity and electromagnetism, and
    can provide an insight into processes determining vertical structure of
    dusty tori surrounding accretion discs. Some of these results are
    summarized also in the paper accepted for the publication in The
    Astrophysical Journal Supplement, scheduled for the March 2013, Volume
    205.
