What is Plasma?

Plasma is one of four fundamental "states of matter". Solid, Liquid, Gas, Plasma.

Plasma is characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is the most abundant form of ordinary matter in the universe, mostly in stars (including the Sun).

Plasma can be artificially generated, for example, by heating a neutral gas or subjecting it to a strong electromagnetic field.
