Magnetohydrodynamics
Magnetohydrodynamics (MHD) is the study of how magnetic fields interact with electrically conducting fluids, such as plasmas. In contexts like solar physics and astrophysics, it helps us understand the behavior of charged particles in stars and space. For example, MHD describes how solar flares and coronal mass ejections occur, driven by magnetic forces. It also plays a crucial role in computational models of cosmic phenomena, allowing scientists to simulate the dynamics of galaxies, accretion disks, and other astrophysical environments where both magnetic fields and fluid motion are significant.

Magnetohydrodynamics (MHD) is the study of how electrically conducting fluids, like plasmas or liquid metals, behave in the presence of magnetic fields. It combines principles from both fluid dynamics and electromagnetism. In MHD, the movement of the fluid can generate electric currents, which in turn create magnetic fields. This interaction affects the fluid's motion and can lead to phenomena like turbulence or waves. MHD is important in various fields, including astrophysics (studying stars and solar winds), engineering (designing processes using liquid metals), and fusion research (confining plasma in fusion reactors).
