The normal field instability under side-wall effects: comparison of experiments and computations
A single spike of ferrofluid in a small cylindrical pool is both computed from first principles and observed by two independent experimental techniques.

Measuring the deformation of a ferrogel sphere in a homogeneous magnetic field
A sphere of a ferrogel, when exposed to a homogeneous magnetic field, gets elongated along the field lines and vibrates after an initial rapid excitation. This is described by a damped harmonic oscillator model, and Poisson's ratio of the gel is deduced.
Response of a ferrofluid to traveling-stripe forcing
Plane waves propagating on the surface of a ferrofluid are excited by a spatially and temporally modulated magnetic field exhibiting a resonance phenomenon similar to that of a forced harmonic oscillator.

Via Hexagons to Squares in Ferrofluids: Experiments on Hysteretic Surface Transformations under Variation of the Normal Magnetic Field
For the hexagon–square transition of the pattern of spikes on the surface of a magnetic liquid, we tailor a set of order parameters like peak-to-peak distance, circularity, angular correlation function and pattern specific amplitudes from Fourier space.

The Surface Topography of a Magnetic Fluid — a Quantitative Comparison between Experiment and Numerical Simulation
The normal field instability in magnetic liquids is investigated experimentally by means of a radioscopic technique which allows a precise measurement of the surface topography, and compared to results obtained by numerical simulations via the finite element method.
