title: Electron magnetohydrodynamic approximations and the magnetic drift wave.
abstract: It is shown that the approximations of electron magnetohydrodynamics (EMHD) are too restrictive to be realistic for at least plasmas of low-Z materials (for example, hydrogen and its isotopes). The simultaneously used assumptions of stationary ions and inertialess electrons are not self-consistent, especially within the framework of local theory. As a result the application of EMHD to describe the pure transverse magnetic drift wave suffers from weaknesses and such a mode does not seem to exist in magnetized plasmas.
