In physics and chemistry, plasma (also called an ionised gas) is an energetic gas-phase state of matter, often referred to as "the fourth state of matter", in which some or all of the electrons in the outer atomic orbitals have become separated from the atom or molecule.
The dynamics of plasmas interacting with external and self-generated magnetic fields are studied in the academic discipline of magnetohydrodynamics.
The ion temperature in a cold plasma is ofter near the ambient temperature.

An important field of plasma physics is the equilibria and stabilityof the plasma.
MHD theory is the simplest representation of a plasma, so MHDstability is a necesity for stable devices to be used for nuclearfusion, specifically magnetic fusion energy.
Beta is a measure of plasma pressure normalized to the magneticfield strength.

Since the space between the stars is filled with a plasma, although a very sparse one (see interstellar and intergalactic medium), essentially the entire volume of the universe is plasma.
The ion temperature in a cold plasma is often near the ambient temperature.
For many purposes the electric field in a plasma may be treated as zero, although when current flows the voltage drop, though small, is finite, and density gradients are usually associated with an electric field according to the Boltzmann relation.

A common fluid treatment of plasmas comes from a combination of the Navier Stokes Equations of fluid mechanics and Maxwell's equations of electromagnetism.
