Based on the background of big data, the paper establishes the evolution equation of electromagnetic fluid state parameters over time called Magnetohydrodynamics (MHD). Compared with kinetic theory, magnetohydrodynamics is much simpler in mathematical processing, and there are many processes in plasma. For some other phenomena in plasma, such as Landau damping, instability in velocity space, etc., the theory of magnetohydrodynamics is unable to describe. The thesis starts from the dynamic equations and establishes the magnetohydrodynamic equations.
