Plasma is a unique state of matter consisting of unbound positive and negative particles, electrically neutral overall. It lacks a defined shape unless confined. Generating plasma involves applying an electrical field to a gas, causing electrons to break free from their orbits around nuclei, creating ions and free-flowing electrons. This imparts key properties like electrical conductivity, magnetic field generation, and responsiveness to external electromagnetic fields.

Sustaining plasma requires continuous energy input, making induction an ideal method for this purpose. Industrial applications of plasma include welding, metal cutting, surface treatments such as plasma spray coating, and etching in microelectronics.
