We consider chiral magnetohydrodynamics, i.e. a finite-temperature system where an axial U(1) current is not conserved due to an Adler-Bell-Jackiw anomaly saturated by the dynamical operator Fμν Fμν. We express this anomaly in terms of the 1-form symmetry associated with magnetic flux conservation and study its realization at finite temperature. We present Euclidean generating functional and dissipative action approaches to the dynamics and reproduce some aspects of chiral MHD phenomenology from an effective theory viewpoint, including the chiral separation and magnetic effects. We also discuss the construction of non-invertible axial symmetry defect operators in our formalism.
