Indeed. One of the unexplored features of the universe are the magnetic fields that stretch across clusters of galaxies. It is proposed that inflation could be responsible for this because, when electrons and protons 1st formed the 1st hydrogen atoms, photons would have scattered off electrons and protons. Being as they are a lot heavier than electrons, the photons would have scattered differently off them, generating small differences in the velocoties of protons and electrons and this would have created electric currents and, therefore, magnetic fields.
