Abstract
The effect of an aligned uniform magnetic field upon the stability of a two-dimensional jet is investigated for large values of the Reynolds number R . The wave-number α and the phase velocity c r of the neutral disturbance are obtained as functions of the Alfven number A , the magnetic Prandtl number γ and R . The critical Alfven number A c is found to be 0.34 for infinite value of α R and it does not exceed this value even for finite values of α R .
