Jackson, David P. Theory, Experiment, and Simulations of a Symmetric Arrangement of Quasi-Two-Dimensional Magnetic Fluid Drops. Journal of Magnetism and Magnetic Materials 289 (2005): 188-191....
We study a ferrofluid in a horizontal Hele-Shaw geometry subjected to a vertical magnetic field. Specifically, we calculate the energy of a single ferrofluid finger using an idealized model for the finger. By minimizing this...
