Abstract
This disclosure relates to a stabilized plasma injector device specifically adapted to incubate, shape and develop plasma under the influence of an adjustable electromagnetic field to provide ignition and further promote energy coupling between the plasma and a combustible mass. The device includes a pair of shaped coils one of which is evaporated to form the plasma and the other coil provides the electromagnetic force field to influence the characteristic arc symmetry and the energy coupling between the plasma and the surrounding combustible mass.
