  Neutrinos rotating around Abelian Higgs strings will generate a neutral
current close to the string. As the string moves through the cosmic plasma, the
velocity kick generated by the motion of the string will enhance the neutrino
current in the wake region. The neutrino current density depends on its
distance from the string and is oscillatory in nature. This leads to neutrino
density gradients in the plasma. Such a flux of neutrinos with periodic density
fluctuations will lead to electron currents in the plasma. The current will act
like a cross-perturbation across the cosmic string wake. The perturbation as
well as the high Reynolds number of the plasma will result in the generation of
magnetic fields in the wake of the cosmic string.
