Abstract
It is shown that a steady‐state current can be sustained by the injection of wave helicity. In generalizing to waves of arbitrary polarizations and damping directions, the wave helicity has to include both a magnetic and a kinetic component. A physical picture is presented describing competing effects on current generation, and a generalized helicity conservation equation is derived that encompasses all the results discovered.Keywords
