Description

If chiral (left-right) asymmetry is present in the plasma, the electric current, parallel to the magnetic field, appears. This is known as "*chiral magnetic effect*". We demonstrate that this effect changes the dynamics of the magnetized relativistic plasma and present the proper equations of chiral relativistic magnetohydrodynamics, containing a new, axion-like, degree of freedom. There results are relevant for generation and evolution of cosmological magnetic fields in the electroweak epoch and are applicable to other relativistic plasmas.
