Plasma Concepts

1.1 Introduction

When a neutral gas is ionized, it behaves as a conductive media. Ionization process is the phenomenon associated with striping electrons from the atoms thus creating the pair of negatively and positively charged particles. Electrical properties of such ionized gas depend on the charged particle density. One of the most important distinctions between the ionized gas and the neutral media is that Coulomb interaction between charged particles determines the dynamic of the gas. Ionized gas is able to conduct the current. This property is of particular interest in the presence of the magnetic field when the interaction of the current and magnetic field leads to electromagnetic body force thus altering its ...
