Abstract

The hydromagnetic stability of an incompressible, inviscid, and two-dimensional jet in the presence of a discontinuity in density and conductivity across the jet surfaces is studied against small and large wavelength disturbances. In the equilibrium state the magnetic field is uniform and aligned with the direction of jet velocity. Study of several different cases shows that discontinuity in density or conductivity or in the product of density and conductivity across the jet surfaces has a stabilizing effect on the jet.
