N2 - A mathematical model, which can predict the electromagnetic and temperature fields and also the shape of a molten silicon drop, has been developed for the improvement and determination of the optimal processing conditions in an electromagnetic levitation (EML) device recently developed to accurately measure the thermophysical properties of molten silicon. As a result, it was found that there exists an unstable state in which the drop was squeezed and then might be collapsed due to the electromagnetic force acting on the sample's surface. Also, the results suggest that the shape of the molten material is not necessarily a perfect sphere under the microgravity environment because of the electromagnetic force due to the heating coil current.
