Magnetohydrodynamics

Japanese: magnetohydrodynamics
Magnetohydrodynamics

...the science that discusses the effect of electromagnetic fields on the movement of fluids. In Japan, it often refers to magnetohydrodynamics (abbreviated MHD), which discusses the effect of magnetic fields on electrically conductive fluids. Generally, when mercury, molten metal, or ionized gas (plasma) moves in a magnetic field, an electromotive force is generated, which causes an electric current to flow and generates an (induced) magnetic field, which changes the magnetic field and affects the movement due to the force that the magnetic field exerts on the electric current.

Japanese:

…電磁場が流体の運動に及ぼす影響を議論する学問。日本では,電気伝導性の流体に対する磁場の影響を論ずる磁気流体力学magnetohydrodynamics(略称MHD)を指すことが多い。一般に水銀や溶融金属,あるいは電離気体(プラズマ)が磁場の中を運動すると起電力が発生し,そのために電流が流れて(誘導)磁場を生じ,その結果磁場を変えるとともに電流に磁場が及ぼす力のために運動が影響される。…
