  In this paper, we delve into the influence of torsion axial pseudo vector on
dark photons in an axion torsionic background, as investigated previously by
Duncan et al[ Nucl Phys B 387:215 (1992)]. Notably, axial torsion, owing to its
significantly greater mass compared to axions, gives rise to magnetic helicity
in torsionful Chern-Simons (CS) electrodynamics, leading to the damping of
magnetic fields. In QCD scale the damping from dark massive photons leads us to
obtain a magnetic field of $10^{-8}$ Gauss, which is approximated the order of
magnitude of magnetic fields at present universe. This result is obtained by
considering that torsion has the value of the 1 MeV at the early universe, and
can be improved to the higher value of $10^{-3}$ Gauss when the axial torsion
0-component is given by $10^{8}$ MeV and the mass of dark photon is
approximated equal to the axion. The axion plays a crucial role in achieving CS
dynamo action arising from axions. This study is useful in deepening our
understanding of fundamental physics, from nuclear interactions to the nature
of dark matter.
