Effect of high frequency magnetic field on the Marangoni convection in the floating zone (FZ) silicon melt has been investigated numerically. The purpose of the study is to clarify the applicability of high frequency magnetic field on the suppression of the Marangoni convection in the FZ silicon melt for the space experiments. The numerically obtained results reveal that the high frequency magnetic field has the damping effect for the Marangoni convection, and is useful to control the melt convection in the space environment. Further, the higher magnetic field frequency is useful to suppress the Marangoni convection due to the skin effect. The impurity distribution in the crystal is also affected by the high frequency magnetic field and the impurity distribution respect to the radial direction becomes rather flat at the mostly suppressed Marangoni convection condition.
