Magnetohydrodynamics

Magnetohydrodynamics (MHD) describes the macroscopic behavior of electrically conducting fluids, including plasmas, liquid metals, and electrolytes. It combines fluid dynamics with electromagnetism to explain how magnetic fields interact with moving conductive media. MHD is fundamental for studying plasma confinement, stability, and large-scale dynamics. In fusion research, MHD instabilities strongly influence plasma performance. In astrophysics, MHD explains phenomena such as solar wind, stellar magnetic fields, and accretion disks. The MHD framework simplifies plasma behavior by treating it as a conducting fluid rather than individual particles. Although approximate, it captures essential collective effects. Magnetohydrodynamics is widely used in laboratory plasma analysis, geophysics, and space science. It provides critical insight into the interaction between magnetic fields and flowing matter.
