Abstract

We investigate the instability in stochastic magnetohydrodynamics caused by pseudotensor counterterms in self-energy \({{\Sigma }^{{b{\kern 1pt} 'b}}}\) at the level of the corresponding field-theoretic formulation. By introducing a homogeneous magnetic field and performing numerical estimates of the two-loop diagrams, we demonstrate that this field stabilizes the system. This supports the turbulent dynamo effect as a mechanism of spontaneous symmetry breaking.
