Abstract

A rotating electromagnetic field generation device including a plurality of electrodes, a plurality of electromagnetic field generators, and a controller. The electromagnetic field generators each have a first electric potential output and a second electric potential output. The controller is configured to dynamically switch the first electric potential output and the second electric potential output of each of the plurality of electromagnetic field generators to corresponding selected ones of the plurality of electrodes thereby projecting at least one electromagnetic field from the plurality of electrodes.
