Ideal MHD is the simplest model to describe the dynamics of
plasmas immersed in a magnetic field. It is concerned with
→ one-fluid magnetohydrodynamics and neglects
→ resistivity.
This theory treats the plasma composed of many
charged particles with locally neutral charge as a continuous single
→ fluid.
Ideal MHD does not provide information on the velocity distribution
and neglects the physics relating to wave-particle interactions, as
does the two-fluid theory as well. It does have the advantage that the
macroscopic dynamics of the → magnetized plasma
can be analyzed in realistic three-dimensional geometries
(K. Nishikawa & M. Wakatani, 2000, Plasma Physics, Springer).

magnetohydrodynamics (MHD) meqnâtohidrotavânik Fr.: magnétohydrodynamique The dynamics of an ionized plasma in the non-relativistic, collisional case. In this description, charge oscillations and high frequency electromagnetic waves are neglected. It is an important field of astrophysics since plasma is one of the commonest forms of matter in the Universe, occurring in stars, planetary magnetospheres, and interplanetary and interstellar space.
