Abstract: Abstract: A Lattice Boltzmann model is developed to account for the competition between surface tension and dipolar interaction in magnetic fluids. The description of the interactions was kept as simple as possible to identify and isolate the nature of the essential interactions in the examined situations. The model is used thereafter in order to simulate the deformation of a magnetic fluid drop under the action of an external magnetic field, as well as the onset of the normal field instability in magnetic fluids. The success of the model, and easily identified deviations, demonstrate that the model is a powerful and versatile tool for the study of magnetic and nonmagnetic fluid systems with interfaces.
