Contribution

It provides a numerical demonstration of stability and proves the existence of non-singular axisymmetric magnetic equilibria, highlighting their potential natural occurrence.

Findings

Magnetic bubbles are stable and attractor solutions.

Existence of compact, non-singular axisymmetric magnetic equilibria is established.

Magnetic bubbles are likely to be found in natural plasma settings.

Abstract

Stability and attractor property of free-floating axisymmetric magnetic bubbles in high-conductivity plasmas is (tentatively, numerically) demonstrated. The existence of compact non-singular axisymmetric magnetic equilibria is proved. Being attractors, the solitary magnetic bubbles should exist in nature.
