- Description
- We search for an amplification mechanism of the seed cosmic magnetic induction by studying a new version of the Dirac's \ae ther 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 {\it geometric amplification}.
