In a foregoing paper the foundations for an electrodynamics of mean fields in turbulently moving electrically conducting media were developed. With the method demonstrated there a special case is treated. The turbulence is supposed to deviate from a homogeneous isotropic one showing reflexion symmetry, only due to a gradient of intensity, i. e. of the mean square velocity. The calculations are carried out for small intensities. As a result, expressions for the modified conductivity introduced for homogeneous turbulence in the foregoing paper are given and discussed. The effect of the intensity gradient is illustrated by a simple example. Furthermore, a possibility is shown for describing the general result in terms of modified conductivity and permeability.
