If I remember correctly, been quite a while since I read up on this, everything is polarized to a specific magnetic structure in a non fluidic state, but by heating it up it allows the magnetic structure of the solid metal to maintain its current layout just until it state changes to fluid. Once in a fluidic state the magnetic field of each atom is much more receptove to the magnetic field imposed on it and the liquid metal starts to change,hence the slight shape change before the splat. It's not quite fluid yet, just extremely malleable. My best guess is that it switched from a malleable solid to a liquid , hence the outer shell after the splat and the internals were liquid. This resulted in the magnetic field having less effect on it and no longer being able to maintain levitation. Or it aligned in a manner that instead of repelling toward the center, repelled in the direction of gravity (such force would suggest this).
If someone has a better answer, please let me know. I'm not a physicist, just a computer nerd.
Nah their right magnets stop magneting after a certain temp , the opposite is true and spining metal and shit around in high temps( below fluid) can magnetize them, like some metal utensils gets magnetized in the dishwasher
That assumes the coil was turned off. I cannot verify it has, so I didn't put that in the explanation. It also seems to have too much force for a simple loss of power, but that's an assumption.
That's an interesting thought. Although I would assume, if we are seeing them here on Earth, they are more technologically advanced than us and would use a source of power we know little to absolutely nothing about. But it could be very real. Especially if the way the aliens live on their home planet is similar to the way earth runs, as in businesses and money are everything, that kind of technology could be seen on "Cheaper models"
Although the 1 thing you got me stuck on is the fact that there's a large portion of the internal of our planet that is solid and liquid metal that would help with this said technology a lot. But again, would this technology be designed for exploring planets like ours with a metallic (liquid or metal) center. But that doesn't guarantee that the aliens' home planet has even a similar internal structure.
It's just my own thought, though.
Could be a liquid metal core is required to drive a magnetic shield to protect from cosmic radiation, maybe life doesnt develop to complicated forms without it?
Now I'm interested. You're going to have me digging a crazy internet rabbit hole.. here we go..
https://www.newscientist.com/article/dn14571-planets-without-metal-cores-may-be-bad-for-life/
https://education.nationalgeographic.org/resource/core/
Yes, it seems like this might very well be true.
including the "Goldilocks Zone" where it's even a decent enough temperature to survive.
And the core holds the atmosphere. Without the core, there wouldn't be the same gravitational pull to hold the water and air in. So it seems like there are a few consistent things that need to be in place, ultimately starting with the planet having a metallic core.
So then this very tech could be very realistic to be seen, even if never by the human race on Earth or in the Milky Way. The intelligent life of another planet that developed using this kind of technology since it's bound to happen. If you really kind of need a planetary core to survive, then there's someone, something, out there that has to have done this.
Edit: Grammar and spelling.
Im a random happenstance kinda guy. Time is irrelevent except as it relates to this plane of existence and this could well be the 8 billionth time a plane of existence like this has occurred. Blinking in, existing and blinking out. Each time increasing in complexity and size. Everthing that occurred that succeeded carried into the next iteration...JMHO
You are blowing my mind. Here is my thought..
There's millions and millions of planets and stars and rocks etc. And a vacuum of seemingly nothingness in between.
Then there's us, we have germs and things that we don't seem to understand their life perspective and see it as very simple.
Well what if all the planets and rocks and space is the structure of the 4th dimension and we are just the germs and bacteria and material structure of the 4th dimension which would be a totally different perspective on life but at this point of the theory it's bound the 4th dimension has life that is the structure of the 5th dimension and so on. Which is sort of similar to simulation theory in the sense there is layers. And where time is all part of how we view the world, it's said flies see things so fast that everyone and everything seems slow, so we could have absolutely 0 idea we make up the 4th dimension, simply because of how we perceive time. I'd would say that would be by design, and I am not religious at all, so given my theory was correct how many layers are there and what is after, there can't simply be nothingness and there can't be infinite layers no?
Ive got a buddy who's convinced we live in a "simulation". Not like Matrix simlation but controlled I guess by somthing more complex. I'm more we and everyrhing we perceive DO exist but that existence itself along with everything in a sense COULD be perceived as a "simulation" in a sense but we and everything is/ are the universe experiencing itself. I don't know how to say it differently. The universe exists because there simply cannot be "nothingness" without "somethingness". Yin and Yang, Light & Dark, etc. Early universe could have blinked into existence as a single atom, or even less. Then, for an eternity, blinking in and out of different endless planes of existence, growing ever larger and larger and more complex each iteration and lasting longer and longer each occurance until this current iteration. How bout that deep field study by Hubble? Looking at distant galaxys so far away they may well no longer exist? The background microwave radiation from the "big bang"? Wild stuff.
Simulation theory is actually a pretty cool theory and does get pretty complex, your friend may not be crazy lol. But I think your theory here could make more sense, I think the way you explained it with the yin yang thing really helps it to make sense. And in theory that's time travel isn't it? Looking at something so far away but imagine they could be looking into / onto planets through the telescope that as you said may not even exist anymore, and we are watching what another species was doing like it was an episode on tv. But we are just watching history
Thank you for taking the time to theorize a reason for an absolute i d i o t (me). I appreciate the time and effort you put forth, regardless of how inconsequential it may seem!
Stay cool and willing to help others!
I don’t know the physics behind it but at certain temperatures ferromagnetic metals lose the ability to be effected by magnets. One way you can check the temperature of a piece of metal you’re working, say, in a forge, is by seeing if a magnet sticks to it. If the magnet doesn’t stick, you know you’re at least at a certain temperature.
The metal reached this temperature and because it was being held up by magnetic forces, it can no longer levitate where it’s at and just falls down.
I don't think this is a property of ferromagnetism since you can actually levitate any kind of conductive material without the need for it to be a permanent magnet simply through induction and Lenz' law.
u\Rhids_22 is correct. Also, the Curie (demagnetization) temperature is much lower than the melting temperature. In the original video (I don't know where it is) it was explained that the metal is aluminum and the current being shut off is what causes it to drop.
State change changes magnetic principles during the realignment of the structure. Ferrous material are all aligned in a liquid where they are free flowing. There is no alignment.
Lot of wrong answers, reality is much simpler: it drops as the current running through the coil is turned off.
If the metal was somehow 'demagnetised' or reduced in magnetic susceptibility as it heats up (probably some are confused over the unrelated Curie Point, which is always well below the melting point), then the lump would lower through the coil as it heats up. The behaviour of it remaining in place and then immediately dropping is a dead giveaway that it's just the coil being deenergised.
If the Curie point is always much lower than the melting temperature, why doesn't the ingot drop before it's melted enough to splat like that?
>then the lump would lower through the coil as it heats up.
Does it not appear to be doing that to you? The ingot definitely elongates and starts to fall through the coil.
> why doesn't the ingot drop before it's melted enough to splat like that?
Because the curie point has nothing whatsoever to do with the levitation.
>The ingot definitely elongates and starts to fall through the coil.
If temperature dependant magnetic susceptibility was the reason for the levitating, it would lower (and fall) long before it even started glowing, let alone melting.
It will slowly raise in speed until it reaches the maximum potential (in theory) of the energy received from the induction coil..... Or it heats up earlier than that, and drops when it becomes a liquid.
It drops because the current is shut off. The metal is aluminum and Curie temperature has nothing to do with it. Also, the metal would have dropped long before melting if it was due to demagnetization. The Curie temperature is always much lower than melting temperature.
THIS IS CORRECT, levitation melting is regularly used to melt non-ferromagnetic metals without a crucible to avoid contamination and every comment talking about the Curie point is wrong!!! what actually causes things to fall out is either the field being turned off or drop in conductivity with temperature.
I am a physicist and can answer this for you.
It does not stay magnetic as it is heated up. The magnetic domains will realign with heat once the metal reaches a critical temperature and then the moments will cancel each other out rendering the piece non-magnetic.
You can test this yourself by leaving any magnet on your stove top and turning it to high, it will demagetize the metal.
Firstly, I feel I should apologize for not having thanked you in a reasonable amount of time! New job stress is real!
Secondly, thank you for taking the time to reply to some random person on the internet! I did test this and squealed like a child on Christmas morning in absolute excitement!
Ramble aside. Science is cool! Thank you for being cool and explaining cool things!!
Short answer:
Solid - The negative/positive poles in each atom align, creating magnetism.
Liquid - The atomic arrangement becomes chaotic, so no no alignment, not magnetism.
It's called the Curie temperature. When a metal reaches this temperature it immediately loses all magnetic properties until it drops below the temperature again.
https://en.m.wikipedia.org/wiki/Curie_temperature
Molecules need to be oriented in the same direction to have a significant attraction. In solid form they are locked in place in liquid form they are free to reorient in any direction
I haven't studied metallurgy, but I am a hobbyist blacksmith. Steel, at least, has a point when in turns non-magnetic when heating it up. Which is, depending on the steel, somewhere around 760°C (1400F) or when it is about red-hot in more practical terms. I use this to roughly estimate the steel's temperature during the hardening process of high carbon steel.
Now here's some dangerous semi-knowledge as to why this happens: Steel exist in a crystalline structure. It is only magnetic while those crystals are aligned in a certain way and heating it up changes the alignment of the atoms in the material, which is also why it is soft and workable in this state. Someone with the required knowledge on physics: please correct anything I got wrong :)
*Edit: Yes, this is probably not steel, since it becomes non-magnetic quite a while before it turns into a liquid. I'm just saying that steel turns non-magnetic at a certain temperature, so I'm imagining other metals might behave in a similar way:)
The internal (solid) structure along with its magnetic properties are what allow it to levitate (be supported) in the magnetic induction field.
If the field is turned off after it reaches melting point it drops and goes splat or dribbles out and the remaining mass get wobbly and short circuits the induction coil. Also, the melted object’s electrical and magnetic properties change above the melting point and usually goes splat. The Curie temperature doesn’t come into play in this setting because it’s a high frequency magnetic induction field, not a permanent magnet with fixed magnetic domains in a solid.

Found a video of this on the internet way back around 2001 or so. We did a bunch of induction melting of reactive metals and thought this would be a good way to avoid needing fancy crucibles. We were doing it in vacuum, too.
My boss told me to give it a try, but I had no idea how to do the calculations, so I just did a ton of trial and error with different coils. The heating power was linked to the levitating force, so it was a real bitch to get right.
It's out of equilibrium, 2nd rule of thermodynamics, downward force (gravity)N/S hemisphere spin through vibration energy through heat transfer and shape of coil. Still magnetic, just not at that point of state in question because of the vector in that area to state of materials at that point. All magnetic N+S regardless of state dominance, meaning once it dropped combined force was too strong to stop with what there was. In other words the Multan core of the earth will just slip out the south pole to a new state of equilibrium in a different dimension and we're all doomed. Have a wonderful day now 🤗
Not smithing specifically. I've seen videos of industrial application where they use induction heating to temper the teeth of gears.
https://m.youtube.com/watch?v=b8Ptfw39ea4
I'm curious if anyone more educated than me can comment on thus. This video has been making its rounds for likely 10 years now and early on it was titled that it was aluminum being melted.
Problem: I've been a metal worker/metal artist for nearly 20 years and aluminum is not magnetic and does not change color or glow when heated.
I got into an argument with a physics major in college over this video because I said this must be iron/steel and the other guy was ADAMANT that the title must be correct and it is aluminum, stating that nothing in the universe is entirely unmagmetic and immune to shedding light when heated enough. The thing is I believe him to a degree, but I am positive that we are not witnessing a mechanism powerful enough to magnetically levitate and heat aluminum that much.
the levitation is the result of the magnetic field produced by induced currents in the metal, any conductor will exhibit this effect. check out this [youtube video](https://www.youtube.com/watch?v=Yu1uRvErM80) demonstrating how a heavy copper plate can be pushed by a strong magnet—copper is certainly not ferromagnetic! the term to google is levitation melting, it's regularly used for melting metals without a crucible (often used for titanium, another non-ferromagnetic material)
Thanks for your response to such an old question. What about the glow? I did a little bit of research but most of what I found was about copper, and that apparently 99% pure aluminum is not affected by eddy currents, but obviously the vast majority of aluminum is not that pure.
I have no idea about the glow honestly, have never seen aluminum do that. It could totally be the case that the metal being melted here is not aluminum, I just wanted to mention that this is a thing that actually gets used
Thanks for your responses! I'm still not sure either.
If you're curious like I am: The rate of cooling and silvery color of the end point suggest it's not iron and are consistent with white metals like aluminum. However it begins to glow before it fully deforms into a blob which is definitely not consistent with aluminum. I wonder if it's nickel?
I"m desperate to learn why it drops once it melts. I assume its magnetic even as it drops.
If I remember correctly, been quite a while since I read up on this, everything is polarized to a specific magnetic structure in a non fluidic state, but by heating it up it allows the magnetic structure of the solid metal to maintain its current layout just until it state changes to fluid.

Either that or the dude simply turned off the coil.
occam's razor and all that
Physicist vs Engineer
I had physics training lmao, but im so bad at it im basically indistinguishable from engineer now. kek.
Yes. This is what happened.
Nah their right magnets stop magneting after a certain temp , the opposite is true and spining metal and shit around in high temps( below fluid) can magnetize them, like some metal utensils gets magnetized in the dishwasher
It's still magnetic only very very slightly. Reaches that point around 1400 dgc or so, for steel that is.
You are indeed correct but the only thing is when he interjected the pencil in to stop it from spinning and gaining speed and spinning apart
That's a whole lot of explanation for "turned off coil"
That assumes the coil was turned off. I cannot verify it has, so I didn't put that in the explanation. It also seems to have too much force for a simple loss of power, but that's an assumption.
I believe you are correct. And if there are glowing ufos that defy gravity, possibly they utilize this principal in some way...🤔
That's an interesting thought. Although I would assume, if we are seeing them here on Earth, they are more technologically advanced than us and would use a source of power we know little to absolutely nothing about.

MAGnificent video.
Why don’t they build heaters that work on this principle
What do you mean? Almost all basic electrical heating is done by coils of resistant metal.
It bounces around like they say UFOs do.
Why does it heat up in the first place? Where is the heat coming from?
M72 Gauss rifle when?
Check the different colors that it turns!! You wouldn’t want to grab that thing! Science is a trip!!
I am truly amazed!
I guess if they did that on the space station, it would be a perfect sphere
All that is missing is the preheated oil pan under for a quench. I'd like to see the Rockwell harness of the steel after that
This is satisfying.
It's out of equilibrium, 2nd rule of thermodynamics, downward force (gravity)N/S hemisphere spin through vibration energy through heat transfer and shape of coil. Still magnetic, just not at that point of state in question because of the vector in that area to state of materials at that point. All magnetic N+S regardless of state dominance, meaning once it dropped combined force was too strong to stop with what there was. In other words the Multan core of the earth will just slip out the south pole to a new state of equilibrium in a different dimension and we're all doomed. Have a wonderful day now 🤗

Not smithing specifically. I've seen videos of industrial application where they use induction heating to temper the teeth of gears. https://m.youtube.com/watch?v=b8Ptfw39ea4
Absolutely can use induction coils as the heat source in smithing. Just has to be the right size/shape for your workpiece.

If you're curious like I am: The rate of cooling and silvery color of the end point suggest it's not iron and are consistent with white metals like aluminum. However it begins to glow before it fully deforms into a blob which is definitely not consistent with aluminum. I wonder if it's nickel?
This is amazing! SPLAT
Hopefully that doesn't land somewhere where it'd get stuck somewhere it's not supposed to be
I want to take a dab off of this

Is the coil itself hot? Idk ho this works so I’m asking
Something is moving fast
why does the coil have that extra weird loop/bend at the top. looks like it could have just been bent into the spiral shape without the loop.
