Claim:
1. A system for melting a raw material, comprising: a vessel made of electrically conductive material, configured and dimensioned for the raw material to be introduced and melted therein; a plasma arc torch configured to melt at least some of the raw material when the raw material is disposed within the vessel to thereby create a molten portion of the material; a power supply configured to supply power to the plasma arc torch such that the plasma arc torch can thereby melt the raw material, wherein the power supply is a direct current power supply and the plasma arc torch is configured to use direct current to melt the material; and an inductor, physically disposed adjacent the vessel, and configured to be electrically disposed in series with the vessel in operation, wherein the inductor is not connected to any additional power source, and is configured to effect electromagnetic stirring of the molten material by interacting with a current of the plasma arc torch in operation.
