我们已经展示了捕捉感应电动势信号的能力。系统地分析了电动势信号的特点。给出了磁流体的体积、大小和传播速度对信号大小和波幅的影响。此外，还进行了感应场的模拟，以提供感生电动势信号的物理信息。这些信号可以潜在地用作测量移动的磁流体液滴或弹状物的移动速度或大小的诊断特征。
We have demonstrated the capabilities to catch the signals of induced electromotive force (EMF). The characteristics of EMF signals are analyzed systematically. Influences of volumes, sizes and travelling velocities of ferrofluids on the magnitudes and wave spans of the signals are presented. In addition, simulations of the induction fields are carried out to provide the physical insights of the induced EMF signals. The signals can be potentially applied as diagnostic characteristics in the measurements of travelling velocities or sizes of moving ferrofluid drops or slugs.
