Light millicharged particles and large scale cosmic magnetic fields
  After a brief review of different types of scenarios suggested for the
solution of the problem of galactic and intergalactic magnetic field
generation, the mechanism based on the electric current induction by
hypothetical millicharged particles interacting with electrons in cosmic medium
is discussed. The proposed model successfully describes observational data. The
new light millicharged particles can contribute from a small fraction up to
100% to the cosmological dark matter.
