Method and device for generating alfven waves

摘要

A method for the generation of Alfvén waves, in which material that can be ionised is produced and passes through a magnetic field, is disclosed. The magnetic field includes a magnetic primary field which is deformed periodically by at least one oscillating magnetic secondary field of the opposite polarity to the primary field. As a result, Alfvén waves are formed in the material which can be ionised and is located in this magnetic field. The Alfvén waves propagate at a velocity (VA) which depends on the mass density of the material passing through the magnetic field and on the field strength of the magnetic field, with the field strength of the magnetic field being greater than the kinetic energy of the material which is located in the magnetic field, so that mass is transported by Alfvén waves.
