Abstract
The instability of the free surface of a ferrofluid subject to an external magnetic field normal to the undisturbed surface is investigated in one dim ension. Using a pertubation analysis up to fifth order in the surface defle ction the character of the bifurcation is elucidated. Moreover, from the am plitudes of the higher harmonics in the pertubation ansatz the approximate static profile of the surface in the non-linear regime is obtained.
