Abstract

Inflationary magnetogenesis does not go well so far. •The over production of the electric field breaks the inflation. •Schwinger effect may remove the cause. • Property of Schwinger effect in dS spacetime is quite different from that in Minkowski spacetime. • Even the negative current appears in 4-dimensional case regardless of the spin of the charged particle.
