                         gas in which a magnetic field has been imposed normal to the 
                         direction of propagation of the disturbance is studied. It is 
                         shown that the amplitudes of the instability (periodic and 
                         aperiodic) due to thermal sources fluctuations vary with the 
                         applied magnetic field strenght. Also, it is shown that the 
                         criterium developed by Glushkov and Kareev for the generation of 
                         acoustic vibrations is a limit condition for this problem.",
