| Abstract: | The MHD ( Magnetohydrodynamic) wave propagation inthe plasma region with the current which is parallel to background magnetic field has been studied,the effect of parallel current on the MHD wave dispersive relation has been explained in this paper,the characteristics of parallel current instability which is generated in the propagation of long wave length MHD has been pointed particularly. |
