The fluid is actually water containing some commercial magnetic particles (small polymer particle containing some Fe2O3 and surrounded by hydrophilic polymer chain for stability). The shape of the metallic object determines the shape of the magnetic fields, hence the structure of the magnetic fluid. We can also notice that the magnetic fields tend to be stronger near sharp edges.
