磁流体动力学(Magnetohydrodynamics,简称MHD)是研究导电流体的流体动力学。这个名字来源于这样一个事实,即导电流体可以携带产生磁场的电流。我们知道,在磁场中,高速运动的电荷q受到一个力的作用。这个关系等价于作用在电流上的力,有趣的是,由于这种相互作用,磁场会改变电流,电流会被反馈到磁场中。
Magnetohydrodynamics (or MHD in short) is the study of the fluid dynamics of conducting fluids. The name originates from the fact that conducting fluids may carry currents that generate magnetic fields. We know that in presence of a magnetic fielda chargeqmoving at velocityis subject to a force. This relation is equivalent to the force acting on a currentthat isand the interesting thing is that, because of this interaction, the magnetic field will change the current that will be fed back into.
