A new mechanism is identified for radio frequency (RF) wave induced force and current drive caused by a kinetic flux carried by coherent oscillations of plasma particles. The induced force along a magnetic field line by RF heating of plasmas is calculated with a one-dimensional slab model, and found to be contributed by the plasma power absorption and spatial inhomogeneity. The inhomogeneity term consists of a kinetic flux and a flux related to RF wave helicity injection rate. The effect from the kinetic flux exists only in a warm plasma, whereas, in contrast, the effect from the helicity related flux exists even in a cold plasma. The forces are calculated for both electrons and ions in the ion cyclotron range of frequencies (ICRF), and the effects from the ion cyclotron and the second harmonic resonance are included.
