    "abstract": "The theory of mean field electrodynamics for diffusive processes in Electron\nMagnetohydrodynamic (EMHD) model is presented. In contrast to\nMagnetohydrodynamics (MHD) the evolution of magnetic field here is governed by\na nonlinear equation in the magnetic field variables. A detailed description of\ndiffusive processes in two dimensions are presented in this paper. In\nparticular, it has been shown analytically that the turbulent magnetic field\ndiffusivity is suppressed from naive quasilinear estimates. It is shown that\nfor complete whisterlization of the spectrum, the turbulent diffusivity\nvanishes. The question of whistlerization of the turbulent spectrum is\ninvestigated numerically, and a reasonable tendency towards whisterlization is\nobserved. Numerical studies also show the suppression of magnetic field\ndiffusivity in accordance with the analytical estimates.",
