Magnetohydrodynamics (MHD)

Magnetohydrodynamics (MHD) is a field of physics that studies how magnetic fields interact with electrically conducting fluids, like plasmas, liquid metals, or salt water. It's similar to how air flows over an airplane wing in aerodynamics, but here the 'air' is a conductive fluid, and 'wings' are magnetic and electric fields. This theory is crucial in areas like designing power generation systems, understanding behavior of stars, and predicting solar flares.
