Abstract
Using a new non-singular solution, it is shown that the production of photons in dilaton electrodynamics in a cosmological setting is greatly increased if the effect of matter creation on the geometry is taken into account. We show that this increment can be related to the problem of the origin of magnetic fields in the universe.
