Plasma confinement refers to the containment of a plasma by various forces at the extreme conditions necessary for thermonuclear fusion reactions. These conditions exist naturally in stars, where they are sustained by the force of gravity. In the laboratory, researchers use strong magnetic fields to confine plasma.
It is an interesting subject and since you appear to have a computer you may want to read up on it. Take are
yet stars still seem to emit heat
