I just think it's neat.
There are quite a few videos on you tube about this. I believe it was copper in this video. In other videos, I have seen different metals.Was that steel? Looked kind of brass colored at first

Inductively heating is a pretty efficient way to heat up ferro-magnetic metal. Hard to tell from the video if that is copper (looks like it at first), if so it must just be radiative? Also wondering what's causing the turbulence--just hot air from the part?This is just a nifty way to melt metal. I'm sure it takes a lot more energy than it's worth but I just think it's neat.
The "turbulence" is nothing more than it bouncing in a magnetic field. Force (gravity) trying to pull it one way and the field pushing it another.Inductively heating is a pretty efficient way to heat up ferro-magnetic metal.

That's what made me think it might be ferromagnetic rather than copper or brass. I wouldn't think copper or brass would be bounced around with a magnetic field. I'd also think that steel would settle down after the temp exceeded the Curie point, so maybe it's just convection currents?The "turbulence" is nothing more than it bouncing in a magnetic field.
