The strongest magnetic fields occur at a 50% MCG and 50% PF mixture.

Fluid interactions contribute to magnetic field amplification.

Abstract

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.
