Have you seen this ???

tell me how ?

It's a trick!

(Actually, I have no idea...)

 

Interesting....

 

man...Don't stick your d*ck in the toaster!

I dunno, my head hurts now

 

Appears that they are generating a magnetic field through the coil and it is generating a strong enough field to levitate the block and induce enough heat to melt it. Appears to be aluminum.

 

Here's the answer in simpler terms than I could put it. It's pretty cool, actually, and I've always wanted to build one.

I used to work in a factory that had machines that would heat drill blanks the same way before going through a forming machine.
It was something to see as you could touch the copper coil with your finger and it wouldn't burn you but if you had a steel sliver in your finger look out..........ouch

 

Aluminum is non-ferrous. That was steel or iron or a derivative.

You can buy one complete at fluxeon.com

 

cool as hell. i want to play

My younger brother used to do something like that with Mexican rope.

 

I was thinking the same thing because it glowed a red color as it melted. most aluminum doesn't.

 

was aluminum...red was the oxidation burning on the surface, since it had oxgen avaliable....they would normally do this in a vaccum, or inert chamber....I do belive this is the process they use for titanium and other un-obtanium alloys....in a strong enough magnetic field aluminum will dance...was working on a starter /generator prototype 15 + years ago that had very strong rare earth magnets in the flywheel...would float a chunk of aluminum across it ....got stuck to a metal workbench when someone(not me) waved it over the bench, magnet side down....company that gave us the work was not amused and said he was luckey to have his fingers....they brougt out a big welder like device and neutralized the magnets momentarily and un -stuck it with a stern warning , not to let it happen again....

 

I think the secret is in that Soviet KGB writing!
