I would've expected the Russians to be behind this.
So, is it like electricity that is heating the steel? And why didn't the pencil burn, isn't molten steel, like, y'know, hot.
Wait a second, is this the prototype of the Iron Curtain?!
Its called induction. It uses magnetic fields.

Not instantly. Graphite is a pretty good insulator and isn't, say, instantly flammable...

The copper coil acts as an electromagnet, but the magnetic field is alternating like AC I believe, so that the steel is molecularity heated. Sort of like when you bend metal back and forth and it gets hot, in this the magnetic field is sort of heating the metal by flowing through the steel and shifting it back and forth changing the polarity I believe. Usually it's running REALLY low voltage but very high current with like 50-60hz like utility frequency I believe.
I'm open for corrections though.
The coil is inducing a current in the metal, causing it to heat up. It's floating because the last turn of the coil is actually inverted (that's why there's a loop in it), so there are 2 opposing magnetic fields meeting at one point. As the induced current inside the metal causes it to be repelled from the inducing field, it gets pushed up until the influence of the other field becomes so strong it gets pushed down again, until you have a force equilibrium.
Holy shit I didn't expect it to fall and splat onto the table, I love how it changes from super hot red to black quickly.
Science is cool as hell!

I think you are severely misunderstanding the temperature at which steel melts.

It's Russian black magic you don't gotta explain shit.
did that shit just melt
Most badass/ dangerous/ inefficient light source ever, and I want one.
We could travel around in tubes with something like this. That'd be so awesome.

No, it'd be fucking hot.

But we're not made of metal
Edit: You guys knew what I meant.

Until you have a power surge and molten steel pours onto your carpet. :v:
SCIENCE!
Weaponize it.
Oh god horrible images of what would happen if that glob of metal landed on your skin, all my nope.
Why brain, why!
Induction heating at its best.

What do you think bones are made of.

iirc the inorganic mineral structure of the bone is a form of calcium apatite called Hydroxylapatite, learned it in my biology class.

Calcium Phosphate also known as bone ash.
