The velocities of the toroidal and poloidal rotations and the plasma potential have been measured during ohmic heating in the TM-4 tokamak. The potential at the center of the plasma column lies between — 100 and — 700 V. The velocities at the center of the column agree with the neoclassical predictions, while those at the periphery are much lower.
