Abstract

We study the spreading of a non wetting ferrofluid drop along a wire. The external control parameter of the magnetic fluid spreading is the magnetic field generated by the current in the conducting wire. For a current threshold we predict a spreading of the drop into a sheath coverage. This magnetic wetting transition is analogous to the wetting transition on a fiber predicted for totally wetting fluid in presence of Van der Waals forces.
