Description
Although turbulent dynamo processes can amplify magnetic fields to the strength observed in astrophysical situations, how seed magnetic fields are generated in the first place is still a mystery. We show that by analyzing the evolution of canonical vorticity that the canonical battery effect is responsible for seed magnetogenesis. The process generalizes popular magnetogenesis mechanisms, namely the Weibel instability and the Biermann battery effect. The canonical battery term allows for the prediction of various other magnetogenesis mechanisms as well. An example of such a configuration, namely 2D-localized pressure anisotropy, is presented.
