Abstract We derive equations for the Green function and the correlation tensor of the magnetic field in the second approximation in the velocity amplitude of the conducting fluid, taking into account the temporal spectrum of the flow. For long times the average magnetic field is damped with time and its turbulent diffusion coefficient is determined by the magnitude of the spectrum at zero frequency. For sufficiently large Reynolds numbers the second moment of the field, particularly its energy, increases exponentially with time.
