We have developed a system for in-situ observation of glass melts under high magnetic field up to 10 T. Thermal convection in binary potassium phosphate melts was observed under vertical and transverse magnetic fields. Above 1 T, the flow velocity of the convection decreased to one-third of the velocity at 0 T in the melt of low potassium content glass by applying vertical and transverse magnetic fields. Contrary to this, the flow velocity increased in the melt of high potassium content glass by applying transverse magnetic fields of around 1 T. It was deduced that different electro-magnetic forces act on positively charged potassium ions and negatively charged clusters consisting of PO4 tetrahedra resulting in the attenuation or acceleration of the flow velocity of the melts.
