The three-dimensional pattern of a molten silicon flow under a magnetic field was revealed by X-ray radiography and large-scale three-dimensional numerical simulation. A flow visualization technique using X-ray radiography and a three-dimensional numerical simulation governed by a magneto-hydrodynamic equation revealed the pattern of the flow to be axisymmetric and under a low magnetic field, whereas the pattern becomes non-axisymmetric and three-dimensional under a high magnetic field even if an axisymmetric temperature boundary condition was applied. The result leads us to understand that the asymmetry originates in the intrinsic instability.
