- Plans at inductionheater... This is a 3 kilowatt induction heater levitating and melting aluminum. A small cylindrical chunk is levitated with 2-2.5kw of input power. I transform it into a molten, glowing ball before releasing it to the ground using the modified induction heater.

This is amazing! Will you teach me how to make this?
I did not know you commented on this video
Search how to make induction heater
yes
sorry, can you say that about 5 more times i didnt get it
Stop spamming
This guy can make a chunk of Aluminum float and melt in thin air... but can't figure out how to focus a simple camcorder.
ChickenTikiMasala cams are hard
+ChickenTikiMasala I call it the relativity of intelligence displacement
so true
That was the single most fascinating thing I've seen in a while!! I've got to show this to hubby, he's going to love it!!
I love that it gets all Sasquatch video at the end
This is amazing! How can I make this?
Damn
rest in peace
This might be a little late, but I think the only thing you need is a strong AC current running threw a copper spool and a pice of aluminum.
Oh and rubber gloves and tools with rubber grips so you don't die from making one wrong movement would also be usefull I think.
But yeah, the equipment needed for this experiment is extremely basic.
The best part is when the aluminum dropped. Best camerawork ever.
I suspect wizards

Could you lower the voltage very slowly so that would cool also while still levitating forming an almost perfectly aluminum solid sphere?
Just drop it on oil
@@anonimoqualquer5503I don't think that's a good idea cheif

Really cool.
I thought once the aluminum obtained molten state the magnetic field would lose levitation effect, was wrong on that one.
Very nice video, thanks for posting.
OMG...All of that waiting and he didn't record the SPLAT!!
i agree - cool stunt - terrible camera work
You'll notice how sciency people often are in complete lack of some basic skill, like talking to other people or driving a car.
lol
That's just what dumb people who think they're smart say. or something along the lines of "I'm not book smart, but at least I have common sense. " 😛
@@DeeHawkDK And sadly, people with basic skills often lack science.
My friend... have you ever considered whether this occurs in outer space at all?
2:18 Captain, the warp core is fully powered!
I would love to see the Hot red aluminum ball and get flat in Hi Speed Camera.
That website has now become my whole day. Thank you for this! I was looking for 'interesting' today :D
"That's really cool, isn't it?"
Hell yeah it is! LOL!
That is so cool.I wonder once it's molten,could you cut back the power to let it solidify and still let it levitate,or would it lose levitation first?In effect,use it to make solid aluminum spheres?
I'm betting it would lose levitation sadly, as there is no independent heat/levitation control
Yes!! I found your channel! I’m not worthy! Friggin genius levels! So much inspiration on innovative processes!
induction is short for "inducing voltage". Does a wire have to be magnetic to carry a current? When you run a transformer by putting a voltage across the primary, is the core or the secondary coil naturally magnetic? So, the answer to you question is "no".
Definitely the most fascinating thing I've ever seen on youtube... Glad I found this by chance :-)
You are correct, the color is primarily down to the filter response on the color filters used in the camera, since the light gets through to the cells in the imaging array that has blue and red filters, the camera will render the color as a pink to purple.
AC current creating a changing magnet field on the coil which induces a current on the metal, because the metal has resistivity, electrical energy is converted to thermal energy. Lens's law keeps the metal floating. One of the most genius uses of grade 12 physics I've seen!
how hard would it be to get it to molt into a semi-perfect sphere and cool it while is hovering?
That would be almost impossible unless perfect conditions lol
I have a pimple underneath my toe nail

Bad camerawork in the end, VERY cool project! Probably something of the coolest thing I have seen.
Yes, it is very cool!!!
You have confirmed what I had imagined that this can be done with copper or aluminium. The one one thing that took me off guard was the intense heating of it. Can levitation of conductive materials be possible without inducing so much heat? Maybe in that set up they kinda of go hand in hand right?
Say, I saw the dance with your kid.... you got the moves like Jagger doc!
Drone: You're new reactor core is ready
Captain: That's garbage, that's not the kind I wanted
Drone: Okay :(
Well, it isn't ferromagnetic like iron, but here it levitates due to the magnetic field generated by the eddy currents being induced within it by the induction heater.
I don't understand how critically heated metal retains its magnetism?
+Robert Wight it doesn't. The levitation coil pushes against eddy currents induced in the work. It is like a transformer with the work as the secondary. As it has currents in it, it can be pushed around by the magnetic fields in the primary.
Aluminum isn't magnetic to begin with.
@@Folopolis yeah

The forbidden Marshmallow
That was magical. Thanks for sharing! Have you had any success with sand casting without a crucible? Or does it drop it too fast?
this is what all those ufo sightings are. they say we got aluminum from aliens.
I took a massive assumption because you didn't understand my sarcasm and you justified the reasoning of this guys spelling even if it didn't need to be justified.
Thank you for having a pencil in this video
can you add more aluminum as this one melts, and see if you could see what shape forms.
The thing is, voltage is the electric potential, and you need a conservative field for potential to be well-defined, and one of the conditions of a conservative field is that the curl is everywhere 0, and induction heaters work by inducing a curl in the electric field as per Maxwell's equations, so voltage is strictly only well-defined when there are no moving charges.
And this is how tinfoil is made...
Hi, that's awesome. How do you achieve the upward reaction force to support the aluminium?
Now that's a bloody cool lightbulb :)
Worst moneyshot ever.
internal resistence and eddy currents are the name of the game.
A really strong alternating electromagnetic field induces eddy currents in the work-piece (that's what heats it as well), and the design of the coil (top going one way, bottom going the other) create opposing forces that keep it centered. Keep in mind that the amount of electromagnetism present is INSANE. Weird things happen at high power levels.
Congratulations! You made Aluminum Foil! That was rad, by the way :)
What the aluminum is thinking: ow. ow. Ow. OW. OWW. OWWWW. OOOWWWW. HOOOOOLLLLYYYY SHHHIIIIIITTTTT!!!!!
And that ladies and gentlemen, is how aluminum foil is made.
After it fell down on the floor it looked like a teddy bear !
Voltage is not meaningless. The coil is the primary. The workpiece is the one-turn secondary. The coil has over 1000A of current which creates the alternating magnetic field which induces a voltage in the workpiece. The workpiece shorts the voltage, creating a massive amount of current in it which heats and melts it. This is the theory behind induction heaters.
Dude you have a career to make in cinema. Great camera work
Aluminum is weakly magnetic-interactive, not a lot. But with enough power, it's amazing what magnetism will and can do to even non-magnetic materials like salt, ice, etc..
All metals are magnetic, but iron has magnetically aligned crystals, which is why it reacts to magnets the way it does.
The coil is alimented by a high powered electricity, so a magnetic field is formed, and put in levitation the aluminium. The high power melt the metal (like the princip of the microwave machine), creating a glowing ball of metal floating in the air between the coil. When the ball falls, it's because the temperature of Curie is reached ( look at that on the net, I don't know how to explain this in english..)
Oh, come on! I just think it was out of focus, since he moved the camera.
Still, it's some pretty amazing video! Did the aluminium go solid again when it touched the cold floor?
this shows a great example of a necleus in an atom
The magnetic fields generated by the copper coil generates eddy current to push the aluminium either up or down, according to the direction of the current. But this current is changing 60000 times a second, so its repeatedly pushes it up and down 60000 times a second, and so it levitates.
wow, I can see the copper bulging from all the heat too. its interesting that it doesn't totally break before the aluminum begins to melt.
No, the copper doesn't bulge, it is liquid cooled so even when the aluminum is molten the copper is barely warm.
but its visibly expanding from the heat.... whatever man. :)
Neverdweller I watched it again skipping around to see where you're seeing that but I'm pretty sure it is just your imagination. :-)
Nevir202 Its science. and I am not seeing things, en.wikipedia.org/wiki/Thermal_expansion
Neverdweller
I am aware of thermal expansion, I am telling you the coil is barely getting hot if at all as it is liquid cooled.
Here is a quote from an FAQ about induction furnaces:
"How hot does the induction coil get?
STEVE: "The induction coil is cool to the touch; the heat that builds up in the coil is constantly cooled with circulating water."
Feel free to read up on them at your earliest convenience.
www.gh-ia.com/faqs.html
Oh! My kingdom for a induction heater that powerful lol... That's really awesome bro 👍
Forgot to ask, did you bend that coil yourself? If so you did an excellent job 👏👍
You should have let the ball drop into water so it cooled in a shape ._.
eh, no, water tends to explode when you drop something really really really hot into it, this one college professor did that very thing dropping thermite into a glass beaker, the water expanded so quickly it shattered the beaker and covered everyone in small glass cuts
eric planting I knew that, but I was thinking maybe a large metal drum could take the expansion :/
I am no science major, nor do I pro-port to be of any kind of scientific mind, but just for practically it could be passed through a water mist chamber stage by stage to cool it down?
I mean.... sure it'd have to be on an industrial scale to make it any level of viable, but with a working proof of concept and then going through R&D towards speed and efficiency through repeated trials could bring it to a well timed machining process right?
I dunno just my two cents no idea if this makes any sense, just wanted to put it out to see if it might have some workable pieces of info.
***** TBH, it'd be easier at that point to just 3d scan the blob whilst it is held in place, then make molds to drop the metal into and cool into shape with.
but I dunno xD
+eric planting it's because of laidenfrost effect
It's just beautiful... Whoever says science is boring is ignorant.
A little research after I made that comment and now I know! Very cool stuff :) Gotta love most of the collective knowledge of the species being only a few keywords and clicks away :)
Hey great...you just killed a Terminator...:)
@lstintxs This one I will address: the cord is powering the the driver circuitry. The high voltage for the inverter is coming from a 30A 10g line, connected to a 240vac line. As far as electricity, my home runs on solar and wind power so my electric bill is zero.
it normally goes into a flat star like shape, like water does when you drop it onto a flap surficeif that makes sense? its because the second it hits the water the impact makes it flat whilst the cold makes it go instantly hard, but somtimes it would do the complete opposite and go into a round ball shape
It is because aluminum becomes a super conductor under that amount of induction... Super conductive metals have the unique composition of diamagnetism.. So both sides somewhat share a pole and they repel in every direction!! You can make levitating metal at home without using induction or anything just using a diamagnetic material (such as catalytic carbon?) over a magnet! :) enjoy!
hello there i have a couple of questions for you
what temperature did you achieve with this?
have you ever tried to maybe to have the coild wrapped around maybe a ceramic container or tube and try this?
3:38 thats some heavy duty bird shit!
dropping this into a mold of some kind would be awsome. gotta take into account of the splash
I also wrote an app for the iPhone, Thermal Light, to measure the temperature of the metal from 1000F-2700F!
@rich1051414 First of all the process of induction heating does not reverse the poles of the object. Also the levitation is caused by the aluminum being diamagnetic meaning that it will take the magnetic field and reflect it back on its source. what happens is that inside the coil the opposing magnetic forces of each winding causes what are called eddy currents which merely jiggle, or "excite", the atoms of the item in the field. This whole process does causes heat to build up in the object.
I think the purple glow is just the camera, and it falls out because they either switched it off or the metal was too molten to be magnetized any longer
at the very end of the link I just gave you I explain the theory behind levitating metal with an induction heater
Nice demonstration. I like your machine.
@lebensraummetal Molten metal projectiles exist - they are employed in 'shaped charges'
all that brain matter and you dont understand the nature of a science experiment, priceless
I think when he said that he intended them to cool. That way the molten metal would form incredibly pointed and fast moving flechettes...
It's possibly his camera. Digital cameras / recorders can pick up infra-red due to the nature of the image sensor and it normally shows as purple in the photos / on screen.
You can see this effect if you get your camera phone and hold a tv remote in front of it whilst pressing a button. You will see a large purple light! If you have an optical mouse that uses an infra red laser it will also show up!
As this is being heated to a high temperature it might be that it is emitting more infrared.
3 Things interest me here:
• Aluminum melts
• The magnetic field affects ALUMINUM
• Aluminum levitates
Bob Bill Practically everything is affected by magnetism if the field is strong enough. look up the levitating frog.
I knew that (I have seen a magnetized aluminum can before) but the coil effects it so strongly.
+Bob Bill a current is induced into the aluminium. It's like a transformer. But it just goes round and round inside the metal cause it isn't connected to any circuit to make it go places. That current is the same or lagging just slightly behind the current in the heating coil. So like magnetic fields repel, enough to levitate it, because it is at the top opening. I expect if it was put in the bottom opening, it would be pushed out of the coil, pushing it down instead of up. But notice that the force on the aluminium in the example shown is still in the direction of pushing it out of the coil. Except it is counterbalanced by gravity in this case. I guess it just falls down to where the field is strong enough to push it out and there is a balance of forces there. The induced currents also are what heat the work up obviously.
EDIT: I fudged it up a bit. The changing magnetic field in the heating coil produces an _opposite_ magnetic field in the work. But if you imagine it, there is say north on the top of the coil and north on the bottom of the work, and so it will be repelled out of the coil. As it is sitting on the top of the coil, it will be levitated up.
There is also a levitation coil apparently, which I don't fully understand. Read the plans. Maybe you can make more sense of than me in my sleep deprived state :)~
Bob Bill ye what’s cool is i’m making one soon but not with an alternating current sadly my magnet isn’t going to make anything fly anytime soon
Once you smelt the metal, you can drop it into a mold and make parts with it.
If you do this process in a vacuum chamber, you can smelt titanium and make close to perfect parts with it. Very little machining needs to be done to clean up the part.
Peace.
Mike..
Even better if you melt aluminum in vacuum chamber and it does NOT get a chance to oxidize, it is highly reactive to water! Of course in the vacuum the water will be boiling... Should still work tho
Yes, this is very cool. I gotta build one now.
I've welded aluminum but didn't know it glowed so brilliantly like that.
Feel like dropping it near all those cords could have been dangerous but that aside drop one into a tall tub of water. See if you can get it to cool before it touches the bottom so it keeps the shape it had in the air.
How does it levitate? I thought aluminum wasn't magnetic? Or are the magnetic fields so great that anything will levitate in there?
I suspect it stops spinning as it becomes molten because the magnetic forces start creating flows within the slug instead of acting on it as a rigid body.
outstanding demo
What kind of a dent does that put in your electric bill?
pretty cool you are running it all from an everyday orange extention cord too.
hi there... very cool work.. gotta give my hat to you :):) may i ask what you done to the inductor to let the alumium drop(audio abit screwed but hey its a cool vid :) )?? (turn up the power or turn down the power?? (had to ask :| )) thanks
That's what lightsabers are made of.
you should try a glass tube under it, so you can funnel the aluminum into a mold
@RabbiAddosso From what I've read it needs to be a conductor as the heat is generated by electrical resistance as current flows through the workpiece. This might not be completely correct.
Its just alot of math and efficiency issues which he covers very well in the discription below, other than that, its just a high power frequency generator
How the hell did I get here? I don't even remember what I originally came on UA-cam for...
Like to see the aluminium cooled as a sphere as a pose to a splat.
its very cool. never seen something like it before. my question is, can you melt other metal like lead, copper or steel?
thanks.
Yes its beyond cool, its damn hot!
Thanks for the Video.
I have seen that you are an expert in induction heating and I would like to do you a question. I have an old induction heating machine and I have prepared a vacuum box to get to melt under vacuum. All work perfect but when the vacuum starts the machine stops and I don´t know why. Could you help me to find the problem? If you need more information or some photos let me know. Thanks
you know, if you can insert a sphere of pure graphite in an iron shell, make it heat at over 3000 °C then make it fall into a rapidly decreasing temperature (cold water) the iron will tremendously compress the graphite pill inside of it in the process then create small diamonds out of the graphite (see james hannay). well, i think that the levitation inductor seems pretty good for this kind of experiments....
i back this up.. im no electrical genius but i can understand how that works to a small extent. so the material does not need to be magnetic but it needs to conductive right?... like i said i dont know much...this is really neat though
I was going to say the exact thing because I had the same doubt for almost a second before realizing the induced field ...
So good job. Can glass be melted and what kind of induction heater can do it ?
If the crucible can conduct current and heat you can indirectly melt glass
i think that it is a really cool thing you should be proud of yourself.
WAIT A SECOND!!! AM I TRIPPIN???
That was cool! Why don't you let the ball fall into a bucket of water next time. Just to see the shape it will take!
What would other metals do? does the aluminum only float because it is lighter? what if you had a compressed air can and lightly cooled it/spin it, how long would it levitate? I have so many questions
it works due to eddy currents, try getting a strong magnet and rolling an aluminium can over it, it will stop. As long as other metals aren't magnetic, and are good conductors of electricity it will work. (I know everything is Paramagnetic or Diamagnetic but it has to be really resisting or attracted to not work.)
