Week 3: Interactions between Charged Particles, Plasma Parameter, Defining Characteristics of a Plasma
In plasma, contrary to the neutral gas, the motion of the particles can cause local concentrations of positive and negative electric charges. These charge concentrations create long-ranged Coulombic fields that affect the motion of charged particles far away from the charge concentrations. Thus elements of the plasma affect each other, even at large separation ns, giving the plasma its characteristic collective behavior.
