Abstract
Ionized gas is provided by a feed tube and is formed into a generally spherical body of plasma having an oscillating magnetic field. Three rotatable wheel-like members are disposed symmetrically about the body of plasma and are rotated in synchronism in such a direction that the portions of the rotatable member adjacent the body of plasma move upwardly and away from the body. The movable members move in planes disposed generally radially of the body of plasma. The movable members each include bands of high permeability material which cooperate with the magnetic field to produce forces of magnetic attraction which retain the body of plasma in a central suspended position spaced from the rotatable members. The lower portions of the rotatable members are cooled by a circulating coolant.
