• The present paper investigates the stability of nondissipative, heterogeneous shear flow in the presence of a uniform magnetic field applied in the streaming direction. The main results established in the paper are the following: (i) The waves propagating along the streaming direction are the most unstable ones and hence the two-dimensional analysis is made throughout. (ii) The complex wave velocity of an arbitrary unstable mode must lie within a semicircle in the upper half plane whose radius is less than the radius of Howard's semi-circle. (iii) If the magnetic force number exceeds certain quantity which depends only upon the streaming velocity, the system is completely stabilized. Further the analysis has also been carried for the case when the applied magnetic field is weak.
