We suggest a new self-consistent Einstein-Maxwell-axion model based on the Lagrangian which is linear in the pseudoscalar (axion) field and its four-gradient and includes the four-vector of macroscopic velocity of the axion system as a whole. We consider extended equations of axion electrodynamics and the modified gravity field equations and discuss nonstationary effects in the phenomenon of optical activity induced by axions. © 2012 Pleiades Publishing, Ltd.
