Abstract
It is shown that the breaking of conformal invariance in quantum electrodynamics due to the trace anomaly results in the generation of long-wave electromagnetic fields during the inflationary stage of the evolution of the Universe. If the coefficient of the logarithmic charge renormalization is large (due to a large number of charged particles species), these primordial electromagnetic fields can be strong enough to create the observed galactic magnetic fields.Keywords
