The gas rotation in moving striations in a longitudinal magnetic field is examined. We study the case when the rotation is caused by the Ampere force affecting the eddy electric current which comes about because of a noncollinearity between gradients of the electron concentration and gradients of the temperature. Relations for the average velocity of gas rotation as a function of plasma parameters in the moving striations are obtained. Based on these relations, the estimations of average velocities are calculated for the typical experimental conditions.
