1. The process of mixing molten metals or alloys by applying an electromagnetic field to produce eddies (movements in streams of fluids in which the currents double back on themselves causing miniature whirlpools).
2. The mixing of molten alloys by exposing the melt to a strong magnetic field while passing direct electrical current between electrodes at opposite ends of the crucible.

The stirring action results from an interaction of the magnetic field of the current-carrying molten alloy with the external transverse magnetic field.
