• The magnetohydrodynamic instability of a streaming fluid jet (radius 7?.) ambientwith streaming liquid is studied to the axisymmetric (m = 0) and the non-axisymmetric(m >1) disturbances (m is the azimuthal wavenumber). When the surface tensioneffect is suppressed; the jet is stable to all m >0 for all wavelengths. In the absence ofthe magnetic field; the model is stable to all m >l for all wavelengths and also stableto m=O if the perturbed wavelength is equal tc>or shorter than 2nR.. While it isunstable only to m = 0 if the perturbed wavelengtln is longer lauan 2nR.. The streaminghas a destabilizing effect. If the magnetic fields are sufficiently high, so that the Alfvenwave velocities are greater than the streaming velocities of the two fluids; the jet isstable against all disturbances and vice versa.
