Field-Reversed Configuration Induced by a Paramagnetic Field

This paper discusses the possibility of paramagnetic field induction inside a partially ionized and weakly magnetized plasma. The paramagnetic field is driven by the azimuthal
E
_r
×
B
drift, where the radial electric field
E
_r
is established as a result of the separation of charged particles induced by axial electron beam injection. Inside the partially ionized and weakly magnetized plasma, the
E
_r
×
B
drift can induce a paramagnetic field
B
_p
with an intensity exceeding that of the external magnetic field
B
_z
. The interaction of these two fields establishes a field-reversed configuration (FRC). The toroidal component of the magnetic field
B
_tor
(produced by an axially directed electron beam) is weak when compared with the
B
_p
field. As a result, the proposed device can be treated as having an FRC.
