![]() MHD physics is found to be important in laboratory plasmas, solar atmosphere, etc. One of the interesting facts is that most catastrophic instabilities are unstable in ideal MHD. Ideal MHD is a good predictor of plasma stability. Ideal MHD describes dynamics reasonably well on large scales MHD traditionally describes macroscopic force balance, equilibria, and dynamics. Let us have a look at a few important applications of Magnetohydrodynamics. There are several applications of MHD physics because of its relativistic study. The ideal MHD equations derived with ideal ohms law and space charges, in the standard form, is given by: The damping waves require some kind of dissipation which will not be considered here. ![]() For convenience, while considering the small waves one should always start with ideal plasmas. The plasma equilibrium can be easily perturbed and as a result of perturbation small amplitude and fluctuations can be excited. A self-consistent set of ideal MHD equations co-relates the plasma mass density ρ, the plasma velocity V, the thermodynamic (also called gaseous or kinetic) pressure P and the magnetic field B. Any movement of conducting material in an external field generates an electric current(I), which in turn induces the magnetic field. In an ideal MHD, the plasma fluid is considered as an electrically conducting fluid and the governing equations of ideal MHD are equations of fluid dynamics and Maxwell’s equations. Magnetohydrodynamics or hydromagnetics couples Maxwell's equations with hydrodynamics to describe the macroscopic behaviour of highly conducting fluids such as plasmas or liquid metals. In this article, we will have an introduction to magnetohydrodynamics along with a discussion of some principles of magnetohydrodynamics. The basic principle behind MHD is that magnetic fields can induce a current in a moving conducting field which in turn polarizes the fluid and as a result changes the magnetic field. Magnetohydrodynamics is abbreviated as MHD. Examples of such magneto fluids are plasma, liquid metal (such as mercury), saltwater and electrolytes. So, also known as magneto-fluid dynamics or hydromagnetics is the study of magnetic properties and behaviour of electrically conducting fluids. The word magnetohydrodynamics is derived from the words magneto (implies magnetic field), hydro (meaning water) and dynamics refer to movement.
