Experimental measurements are reported on the behavior of a laboratory scale ESR unit, operated both in the presence and the absence of an externally imposed electromagnetic field.The main findings were the following:-The imposition of an external magnetic field resulted in quite vigorous stirring, which was manifested by a rapid rotational motion of both the slag and the metal phases.-The apparent metal pool depth was found to increase with increased stirring intensity.-The formation of hydrogen blow holes could be suppressed by vigorous stirring, but the formation o f CO blowholes was not materially effected. -The externally imposed stirring strongly promoted the formation of equiaxed solidification structures.-A mathematical representation has been developed to interpret these results.
