介绍了一种测量导电流体中稳态和非稳态流动的方法。在该方法中，流动区域经受外部施加的弱磁场B-0。流体流过B-0磁力线产生的感应磁场B用于流动研究。它可以在流动区域外测量，优点是不需要与流体的电气或机械连接。实验结果得到了与时间相关的三维数值模拟的证实。它表明如何流体流动配置可以推导出一个适当的测量的诱导场B。
A measurement method is introduced which can detect steady and unsteady flow in electrically conducting fluids. In this method, the flow region is subjected to an externally applied weak magnetic field B-0. The induced magnetic field b generated by fluid flow across the field lines of B-0 is used for the flow investigations. It can be measured outside the flow region with the advantage that neither electrical nor mechanical connections with the fluid are necessary. The results obtained by the experiment are confirmed by a time-dependent three-dimensional numerical simulation. It is indicated how fluid flow configurations could be deduced by an appropriate measurement of the induced field b.
