Reply to "Comments on Origin of cosmic magnetic fields"
  In "L. Campanelli, arXiv:1304.6534 [astro-ph.CO]", we have shown that cosmic
magnetic fields are a natural consequence of inflation. Our results have been
criticized in the recent comment "R. Durrer, G. Marozzi and M. Rinaldi,
arXiv:1305.3192 [astro-ph.CO]." We show that the arguments raised against the
validity of our results are physically and mathematically unfounded.
