This paper presents the hybrid finite element and boundary element method (FEM-BEM) with a level set method (LSM) for the analysis of a free surface deformed in the alternating current magnetic field. Three-dimensional numerical simulations In the floating zone (FZ) method under microgravity are carried out to investigate the deformation process of a silicon liquid bridge with two types of coil positions, the upper case and the middle case. The results clearly show the deformation processes. The liquid parts which are the same position as each coil yield to pressure caused by strong Lorentz force and both ends swell out. This phenomenon conforms well to behavior of melt in the real growing process qualitatively.
