About Induction Heating
Can you explain induction levitation melting?
Observed during vacuum induction melting of metals...
Induction heating coils create a magnetic field. This magnetic field interacts with the molten metal to create eddy currents. There is magnetic levitation due the magnetic field in the molten metal. Since the magnetic field drops in intensity with distance from the coil, the molten metal jumps in and out of the magnetic field.
