The viscosity and surface tension of liquid metals are important properties, both from a scientific and a technological point of view. Conventional techniques involve contact with the liquid whose properties are being measured, resulting in contamination and making undercooling impossible. For these reasons electromagnetic levitation was used to position, heat, and deform the samples in a containerless fashion. In order to eliminate the turbulent fluid flow inherent in earthbound levitation experiments to make viscosity measurement possible and determine the effect of magnetic fields on surface tension measurements, the experiments were performed in microgravity as part of the IML-2 Space Shuttle mission in July 1994. In order to rationally plan these experiments, a substantial mathematical modeling effort was performed. We have developed a computational methodology and calculated the levitation forces, stirring forces, and deformation of the sample through the solution of Maxwell's electromagnetic field equations and th
