Enhanced Coreless Induction Furnace Stirring

An apparatus for stirring a molten or semi-molten material that is subjected to a magnetic field formed by an energized induction coil, said apparatus including a container having a cavity designed to contain said material, said induction coil including a first induction coil section that is at least partially positioned about said cavity of said container, said first induction coil section is configured to create a magnetic field when energized that affects said material in said cavity and causes said material in said cavity to be stirred, and a power supply that energizes said first induction coil section, said first induction coil section positioned at least partially about an outer perimeter of said container, said first induction coil section positioned along a longitudinal length of said cavity such that when said first induction coil section is energized so as to be the only portion of said induction coil to cause said material in said cavity to be stirred, at least 10% of a longitudinal height of said material in said cavity that is measured along said longitudinal length of said cavity is positioned above or below said energized first induction coil section.
