  It is shown that, in the presence of a magnetic field, a quantized vortex
line in a superfluid liquid acquires a linear polarization charge, which is
localized near the vortex axis over a length on the order of the coherence
length. It is found that the total charge of a rectilinear vortex is nonzero,
while the vortex pair and vortex ring have a nonzero dipole moment. The
electric fields of rectilinear vortices near the end surface of a cylindrical
vessel filled with a superfluid liquid are calculated. The electric
polarization of superfluid systems in the presence of thermally activated
vortex pairs and vortex rings has been studied. It is shown that such a
polarization arises in the presence of relative motion of the normal and
superfluid components.
