Abstract

It is shown that the ac helicity injection current drive described by Jensen and Chu and by Bevir and Gray can alternately be deduced from the pseudoelectric field ~<[bold U]-tilde ×[bold B]-tilde>/c produced by oscillating velocity and magnetic field vectors [bold U]-tilde and [bold B]-tilde (here < > denote time average).
