چکیده مقاله:

In this paper, the fluid of cylindrical column magma is intended to upwards, and it is the MHDenvironment, that is located the in the Earth's magnetic field. Our desired fluid MHD, Newton flow iscompressibility the fluid equations, equations of momentum, energy and Maxwell's equations, undernew conditions there is for its. For a point on the surface of the a cylindrical duct, and for a moleculewith respect to the variable density of charge, we gain polarization. By calculating the changes in densitycharge and whit having relation polarization for a molecule𝐌𝐠𝟐𝐒𝐢𝐎𝟒. that abundance is greater thanother molecules in the magma. Change density of charge calculated. With the help of Maxwell'sequations we gain electric and magnetic fields resulting from these changes. Computation is obtainedanalytically in the cylindrical device by applying the assumptions. During computation can be obtainedenergy equation momentum of equation of state fluid magma. Calculate the Poynting vector shows thatthis wave is created published to out. Dispersion equation shows how changes these waves. Finally becalculated power radiation electromagnetic wave.
