Plasma presents characteristics that do not occur in solids, liquids, or gases, so it is considered another State of aggregation of matter. As gas, plasma does not have a form or volume, unless it is enclosed in a container; But unlike the gas in that there are no important collective effects, plasma under the influence of a magnetic field can form structures such as filaments, beams and double layers. Atoms in this State move freely; higher temperature more quickly move atoms in the gas, and at the time of collision speed is so high that a detachment of electrons occurs.
