Effect of a superimposed DC magnetic field on the melt flow in an induction furnace experimental model

The unsteady flow field has been studied experimentally in a cold metal
model of an existing 10 kHz induction furnace for the inter-metallic fibre
extraction process in presence of a DC magnetic field. It has been shown
that a vertical DC magnetic field normal to the free liquid metal surface
efficiently decreases turbulence in the melt volume and suppresses surface
deformations. Whereas the turbulence and free surface deformations were not
suppressed by a DC field parallel to the free surface.
