So.. this is what a flux capacitor does!

#2 No man, flux capacitor makes you travel in time. This is something different.

What kind of a experiment is this?? Appreciate if someone can explain... :|

Its using a magnetic field to create induction heating. The magnetic field levitates it and heats it.

Floating liquid metal in an Induction Coil, holding it in the middel because of the magnetic field. How cool can science be :D

Science is not a sacred cow.
Science is a horse.
Don't worship it.
Feed it.

So this is why i have to extend the cord all the way to its limit on a vacuum cleaner, so it does not create heat with the coiled up leed and catch alight ?

Really awesome video.

Nope.. The induction coil is dependent on the "rate of switching" i.e. Frequency.. A mains line is 230V-50Hz whereas an induction coil uses high current and frequency of switching of the order 100,000Hz . And factoring in all the other requirements, at best you would get a weak magnetic feild with a coiled cord let alone heat and fire..
BTW: why do you need to extend the cord all the way ? :|

I wonder what would happen if you suspended the pop group 'One Direction' in an induction coil. Would it fall through the middle eventually or not?

That is not entirely correct, I have been at construction sites where they have had rolls of cable melting down and occationaly caught fire due to not extending the cord all the way. So yes, it can happend.

Oh yeah, great vid :D

I think the force what heats it is called "Eddy currents" if i am right.

@13 i bought 12 mtr of cristmas lights once. i was so lazy and didnt roll it out. i just hang it on the wall, after 1 hour it catches fire.
learned my lesson there, always roll out a cord of electric wire.
a 12 volt light bolt isnt that dangerous. but 250 of them on 1 wire......

I love science, but this was kinda boring..

#15. Yes I agree. I've had a 50 metre extension cable go 'pop' when I was too lazy to unwind it while using it to power a 1Kw convector heater. Costly mistake! :S

@18: If they were powered by DC (no matter what voltage) the reason for catching fire was insufficient cooling, not the induction ;). Seen the "max. 40W" label on some kind of lamps? That's there for the similar reason - because of the desing and expected use.

It must be the metal with the lowest melting temperature, sodium. (Na).

Actually I made a mistake its an Induction Heater.. oops... my bad
