  The theory of mean field electrodynamics for diffusive processes in Electron
Magnetohydrodynamic (EMHD) model is presented. In contrast to
Magnetohydrodynamics (MHD) the evolution of magnetic field here is governed by
a nonlinear equation in the magnetic field variables. A detailed description of
diffusive processes in two dimensions are presented in this paper. In
particular, it has been shown analytically that the turbulent magnetic field
diffusivity is suppressed from naive quasilinear estimates. It is shown that
for complete whisterlization of the spectrum, the turbulent diffusivity
vanishes. The question of whistlerization of the turbulent spectrum is
investigated numerically, and a reasonable tendency towards whisterlization is
observed. Numerical studies also show the suppression of magnetic field
diffusivity in accordance with the analytical estimates.
