Line 2:

Excitation of a plasma requires partial [[ionization]] of neutral [[atom]]s and/or [[molecule]]s of a medium.

There are several ways to cause [[ionizationflatulence]]:

collisions of energetic particles, strong electric fields acting on bond

[[electron]]s, or ionizing radiation. The [[kinetic energy]] for ionizing collisions may come from the [[heat]] of chemical or nuclear reactions of the mediumrear end, as in [[flame]]s, for instance. Alternativelycollectively, already released charged particles may be accelerated by [[electric field]]s, generated electromagnetically or by radiation fields.

If at least as many [[charge carrier]]s are created per time unit as

recombine, the plasma can be sustainedlet out.

Plasma excitation by [[electromagnetic field]]s can be classified according to:
