通过时空调制磁场在铁磁流体层中实现非接触泵送机制。由此产生的压力梯度导致液体斜坡，其通过X射线测量。如果实现表面波与驱动的共振，则传输机制工作得最好。这种行为可以通过考虑流体的受磁影响的色散关系来理解。
A contactless pumping mechanism is realized in a layer of ferrofluid via a spatiotemporally modulated magnetic field. The resulting pressure gradient leads to a liquid ramp, which is measured by means of x-rays. The transport mechanism works best if a resonance of the surface waves with the driving is achieved. The behavior can be understood by considering the magnetically influenced dispersion relation of the fluid.
