  The hall current in the periphery of a filamentary plasma with the inwardly
directed radial electric field, Er has been investigated experimentally by
utilizing a TPD type dc discharge. When the cusp magnetic filed B$\theta$ is
applied perpendicular to the stationary background magnetic field Bz, the hall
current by the ErxB$\theta$ drift of electrons is induced in the periphery of
the magnetized filamentary plasma.
