Abstract
Primordial magnetic fields seem to be a generic relic of phase transit ions in the early universe. We consider a primordial electromagnetic f ield formed as a result of a second-order phase transition, and show t hat it is stable to thermal fluctuations in the period immediately fol lowing. We also show how such a field arises in first order phase tran sitions. In both cases there is a transitive electric field produced d uring the transition.
