The effect of magnetic and electric fields on quasiunidimensional flow of a perfectly conducting fluid through a duct does not modify it. This effect is important for imperfectly conducting fluids, and allows: non uniform, stationary flows tn a duct with constant cross-section; transonic flows with sonic point at non extremum cross-section, in ducts with slowly varying cross- section; and increased acceleration by means of an appropriate magnetic field. The stability of these flows is also studied for second order pertubations which do not modify the quasiunidimensional character of the flow. It is seen that, whatever the electric conductivity be, choking appears in decelerated transonic flows. (auth)
