Beltrami-like fields created by baroclinic effect in two-fluid plasmas

TL;DR

This paper presents a theory explaining how magnetic fields can be generated in two-fluid plasmas through baroclinic effects, without needing initial seed fields, with applications to laser-induced plasmas.

Contribution

It introduces a new theoretical model for Beltrami-like fields in two-fluid plasmas caused by baroclinic effects, matching experimental observations.

Findings

The model explains magnetic field generation without seed fields.

Predicted magnetic field strengths agree with experimental data.

Coupled flow and field grow simultaneously in the plasma.

Abstract

A theory of two-dimensional plasma evolution with Beltrami-like flow and field due to baroclinic effect has been presented. Particular solution of the nonlinear two-fluid equations is obtained. This simple model can explain the generation of magnetic field without assuming the presence of a seed in the system. Coupled field and flow naturally grow together. The theory has been applied to estimate B-field in laser-induced plasmas and the result is in good agreement with experimental values.
