  We examine magnetogenesis in a multi-fluid environment. We find that the
various composition of a modified Chaplygin Gas (MCG) and Plasma Fluid (PF)
yield magnetic fields of non-negligible strengths. These fields are produced by
the battery effect and interactions between the two fluids may explain the
amplification observed in the simulation. Our simulations show that the
strongest fields are generated in a mixture with 50% MCG and 50% PF.
