Abstract
A numerical calculation is performed for a MHD flow in a magnetic field periodically varying along the flow. An M-shaped velocity atructure is obtained which confirms the "cumulative effect" of distortions of the velocity profile when the flow passes through a number of successive amplitudes of the field. It is shown that in spite of the M-shaped velocity structure, the streamline of the fluid is practically straight.
