How does this work?? I assume that the big wire has a big ac current going through it, making an electro-magnetic field around it, then what happens? The magnetic field agitates the metal inside the crucible, like a metal microwave (does that mean it only work on magnetic metals)? Or does the field make an electric field that acts on the crucible, i dont even know if that makes sense.
