Abstract
The dynamo effect due to low-frequency oscillations and its application to the nonresonant current drive are examined. The relevant single particle forces are analyzed and the possibility of the dynamo effect enhancement by thermal effects is investigated. In the collisional two-fluid theory with isotropic pressure the flux-surface averaged parallel dynamo field is found to be solely due to frictional forces. In the collisionless, double-adiabatic approximation the previously reported steady-state collisionless α-effect is shown to be absent. The origin of this discrepancy is discussed.Keywords
