Abstract

We search for an amplification mechanism of the seed cosmic magnetic induction by studying a new version of the Dirac's aether in a curved cosmological background. We find that an amplification takes place if the scale factor R(t) varies with the cosmic time, which brings to the magnetic field the effect of a geometric amplification.
