Influence of surface tension on the conical miniscus of a magnetic fluid in the field of a current-carrying wire
Thomas John, Dirk Rannacher, Andreas Engel
We study the influence of surface tension on the shape of the conical miniscus built up by a magnetic fluid surrounding a current-carrying wire. Minimization of the total energy of…

Double Rosensweig instability in a ferrofluid sandwich structure
Dirk Rannacher, Andreas Engel
We consider a horizontal ferrofluid layer sandwiched between two layers of immiscible non-magnetic fluids. In a sufficiently strong vertical magnetic field the flat interfaces betw…
