A note on the magnetic spatial forcing of a ferrofluid layer
Thomas Friedrich, Adrian Lange, Ingo Rehberg +1
We report on the response of a thin layer of ferrofluid to a spatially modulated magnetic field. This field is generated by means of a constant current in a special arrangement of…
Magnetic traveling-stripe-forcing: enhanced transport in the advent of the Rosensweig instability
Thomas Friedrich, Ingo Rehberg, Reinhard Richter
A new kind of contactless pumping mechanism is realized in a layer of ferrofluid via a spatio-temporally modulated magnetic field. The resulting pressure gradient leads to a liquid…
Rolling ferrofluid drop on the surface of a liquid
V. Sterr, R. Krauss, K. I. Morozov +3
We report on the controlled transport of drops of magnetic liquid, which are swimming on top of a non-magnetic liquid layer. A magnetic field which is rotating in a vertical plane…
Fluid pumped by magnetic stress
Robert Krauss, Mario Liu, Bert Reimann +2
A magnetic field rotating on the free surface of a ferrofluid layer is shown to induce considerable fluid motion toward the direction the field is rolling. The measured flow veloci…
