Application of a Magnetic Flux in the Corona Discharge Region to Improve Ion Thrust via Ion Acceleration

This paper presents the experimental results of a study on ion thrust under magnetic flux density in atmospheric conditions. This study demonstrates that magnetic flux density perpendicular to the direction of ion flow generates a Lorentz-force. The effect of this electromagnetic force on the flow rate distribution was measured via experimentation. Consequently, it was confirmed that the magnetic flux density by the magnets increased the thrust force by 46% compared to the case without magnetic flux density. On the other hand, the discharge current was reduced by 11% due to the third electrode effect of the magnets.
