The Tohoku University Heliac (TU-Heliac) surveyed the effects of island width on poloidal plasma flow. We determine that poloidal flow is driven externally by hot cathode biasing and an m = 3 magnetic island was produced by two pairs of external perturbation field coils. The electrode current required for poloidal flow at the plasma periphery jumping point increases with island width expansion and shows weak dependency at the core region of the plasma. These dependencies suggest that the magnetic island located at the plasma periphery affects poloidal flow as a drag term.
