Within the scope of the 8th ESA Student Parabolic Flight Campaign 2005 we performed an experiment about the behaviour of ferrofluids. The experiment consists of a ferrofluid which is placed in the homogenous magnetic field of a pair of magnetic coils and is observed with two video cameras to later construct 3-D models. The experiment rest frame is kept at a constant orientation in space by a guiding system based on an ESP-sensor. The external magnetic field is varied and the resulting motion of the ferrofluid is recorded with and without gravity. The analysis shows that the theoretical investigations about ferrofluids make correct, predictions about the influence of gravity for the motion and shape of a ferrofluid. As a main technical result we can recommend our stabilising system to other groups with acceleration susceptible experiments. The ESP-sensor provides an easy and sensitive method to implement position control. Copyright IAF/IAA. All rights reserved.
