FantasmaNaranja, I have good news, lignum vitae wood is VERY resistant to rot, and there are metals (like rhenium and platinum) that just will NOT corrode, (but these metals are expensive.
Where did you get that huge copper pipe? None of the local hardware stores sells pipe larger than 3/4in. That 2 in pipe would be perfect for a project of mine!
It's only 1" diameter, the video must make it look larger. You can get large copper pipes locally though if you look around for plumbing/HVAC supply stores that cater to professionals. It's too bad you can't count on regular hardware stores for that sort of thing.
I'm leaving a comment because you said that reading them is your favorite thing. Your video turned me on to Bismuth as an element and the idea of diamagentism. It's 2:41 am, and I have work tomorrow, and I'm researching obscure magnetic properties. Damn you, internet. I also want to say that I really appreciated the methodical and patient approach you took to making this, showing us each step and explaining everything along the way. If only every scientist in the world were as thorough.
Well i said that pyrolitic graphite is better because you can run it on a circular track. So he wants to make a track instead of 2 chunks of bismuth which are hard to tune.
This seems like a really project that would be fun to watch, but there are some problems in the title that the video claims. I don't know if I'd call this 'indefinite' levitation, as the magnetic properties of the bismuth will eventually decay over time. Also, there is energy being here, but because of the lower friction within the field, the magnet can spin for longer amounts of time. However, this too will eventually stop spinning. The energy, though relatively small, comes from the force of the push that starts the magnet on its way. For this truly to have no energy cost, it would have to have an efficiency of over 100% and the energy would have to come from nowhere, which breaks the second law of thermodynamics. Again, this is a really awesome project that is definitely fun to watch.
Hi:) this is definitely one of your best! thankyou for making all these abstract masterpieces! they're fantastic gift ideas that are unique and that easily take the spotlight. Thankyou for all that you are..and even though I don't know you, you're one of the best people I know:)
The internet has created a lot of misunderstanding about "diamagnetic". What it means is it generates an opposing magnetic field if it is exposed to a CHANGING magnetic field. In a static field, it does not. That can be either motion, or an electromagnet powered by alternating current. In this case, the person placing the magnet near the bismuth supplies the initial energy. Irregularities in the shape of the magnet and the bismuth could keep the field fluctuating for quite a while, but I think it's still stored energy that would eventually "run down" mainly due to the friction of the air. It would take a while. Aluminum has the same property, just not as much.
You're confusing diamagnetism for magnetic induction (which requires a changing magnetic field). Diamagnetism doesn't require an input of energy in the same way gravity doesn't require an input of energy, it's just a static force.
When he said "my favourite elements" it sounded weird... But then I've realised that everyone has his own favourite element: mine is gold, Kim Jong Un's is plutonium, etc
You and what you do are simply amazing! If you aren't, you should be a teacher; you're real good at it and at keeping subjects fun and interesting which keeps the attention of those to whom you impart your knowledge.
The crystals looked amazing Could you get it to work the other way round with a cool bismuth crystal floating... Take a bit of technical electronics but sure you could come up with a way..
Would making both the bismuth pieces sightly convex on the side facing the magnet help? In the same way belts sander wheels are angled, and car belts? I dont know the correct physics jargon, but feel two slightly convex surfaces would reduce the amount of time needed to fine tune your beautiful piece of art
cant begin to describe my pleasure in your content, explantion and entire vibe. You are a king. one question- i understand that free energy is not possible, or at least thats consensus of all credible people with expertise. Can you please explain why this model could not generate electricity if a copper wire was placed correctly near it? I thought that electricity required a magnetic field, a conductor and motion. As all three could happen here without friction, or other energy loss, what would be the reason why it could not produce a current indefinitely? Thanks!
Absolutely gorgeous!! You truly know how to create some awesome videos and the music is very classy as well!! Can you tell me where I can find some Bismuth? Can I purchase this stuff?.....And thank you very much for sharing your knowledge!
This is an awesome project, can't wait to try it. what do you think would be required, what size changes do you think, to be able to increase the size of your spinning magnet. Do you think the bismuth would need to be thicker or a more powerful top magnet?
hey NightHawkInLight you should do a video in how to make borax crystals but try to spice it up in your own epic way :D add stuff to it and see what looks better (just a idea)
What would happen if you coated the magnetic directly with bismith? I can't help but feel but you have something close to how Earth maintains its orbit while also producing its own magnetic field.
Could this be scaled up? I'm thinking of something the size of a shop sign. If you got a stronger magnet I believe you could make a slightly smaller magnet hold up a paper cube or something similar. Would make for great decorations.
What about servo assisted mag Lev? Using just magnets and extremely fast servos and gyros I think it could hold aloft a magnet by oscillating between being too close and too far.
Great video. Looking to experiment with different shaped magnets. What magnet shapes did you try to levitate and what is your best recommendation of size, shape etc. Have you tried a round (ball bearing) type of magnet? Your link for the 1/4" cubes is listed as an N40 grade. Would a same sized N52 provide a greater levitation height? Thanks for an answers you may provide.
Impressive project, but I was disappointed to see that the diamagnetic effect of the bismuth itself was not strong enough to cause the magnet to levitate.
The only "unassisted" diamagnetic levitation I know of is a small ~0.5mm thick piece of pyrolytic graphite, which can be stably levitated about a millimeter above a 2x2 array of neodymium magnets.
Gaaaaaaaaaaah your house must be the coolest place ever. I would frolic through it, and touch everything. When you pour the bismuth, it looks beautiful.
I saw the Bismuth Levitator video Ernie made in the past. A very good video, but of course your video shined bright due to your excellent camera work & editing, well crafted device, and clearly spoken words. A+
@beepybeetle. Rather than your 1.9x10^19 years for Bi-209, I would prefer to say "a billion times the current age of the universe itself." Or, expressed as mean average lifetime (which is the half-life divided by 0.693), we would have 2.7x10^19 years, which is to say, "two billion times the current age of the universe." One reason I like bismuth is that it 'forces' the physicist to stop hiding behind the term 'stable', which is applied to the nonradioactive elements and which has a needlessly clinical, bureaucratic, cautious, soulless, antiseptic quality about it, and instead admit that atoms are, for all practical purposes, eternal -- as in "they last for two billion times the current age of the universe -- OR, for those that are not radioactive the way Bi-209 is, even longer than that."

You shuld do a give away of your art work :D, it just so amazing, kinda look like a desk "toy" like the balls that hit each pther and so on
+NightHawkInLight What a simple and elegant toy!
the sad thing is since its made of wood it will rot before the hundred years pass by (also metal rusts yadda yadda)
FantasmaNaranja, I have good news, lignum vitae wood is VERY resistant to rot, and there are metals (like rhenium and platinum) that just will NOT corrode, (but these metals are expensive.
+NightHawkInLight Isn't bismuth slightly toxic and radioactive?

Sup Cody!
you can buy it at any refrigeration wholesaler
Create a levitating vehicle, Cody! Please!
I once drank bismuth, but it was in the form of a pink liquid and it made my stomach feel better.

Peter Kapica he is talking about pepto-bismol
Pepto bismuth :D
That stuff dont have bismuth in it

The final result you got in the video should be in an art gallery. It looks so cool and the great thing is it has some form of movement in it.
It should be on my bookcase.
Another toy for my big deal executive desk .
Wow... there is no way I am not making this!
Nerd Herd
You want a reason? Just google diamagnetic track
Ulim151 he said NO way I am NOT making this
it's a double negative
therefore it is "I am absolutely making this"
Well i said that pyrolitic graphite is better because you can run it on a circular track. So he wants to make a track instead of 2 chunks of bismuth which are hard to tune.
Ummmm yeah no you didn't say anything close to that
Naim Mazlan in the first comment i meant : You want a reason not to make the bismuth thing? Just google diamagnetic track thats better.
i dont know how i missed this video for so long. As always, greatful to have been able to share this. THANK YOU
This is super cool night hawkin!!!!!! Thanks for the video!

Nice Video. Unique design for your bismuth stand. Insulation and sloooow cooling is the key to nice big crystals.
I wish I had seen this back when I was in school! Dope science project

Again, this is a really awesome project that is definitely fun to watch.
The most intriguing aspect of this experiment is not that the object floats, but that the object gyroscopically ROTATES indefinitely.
Very interesting science project
I'm going to have to do a project with bismuth... this stuff is too cool looking! Thanks for the vids.
Wow. Give this man a nobel prize!!
Bismuth is my favorit element and thats my favorit build with it great job

Reminds me of ufo👽. Maybe we will have aircraft like that one day!!!🛸Amazing video. Art and science at its best!!🤯👍💥👏👏👏👏
I wonder if you could construct a magnetic fan with this - flattened out magnet with blades and larger bismuth. It would be a visual delight!
The crystals looked amazing
Could you get it to work the other way round with a cool bismuth crystal floating...
Take a bit of technical electronics but sure you could come up with a way..
this is a realy cool concept, do you think you could make the top bismuth higher so the magnet would be floating higher? if so that would be so cool.
Man this stuff is so interesting to watch
Try using compressed air like those dusters to get it really spinning! My guess is 3 hours till it stops. I'm probably wrong, it'll go all day..
TOTALLY AWESOME!!! This is so cool! can't wait to see what you have next!
you just earned yourself a subscriber
I'm definitely gonna make a desk toy with this!!

Very cool! I wonder why you have to remove the slag each time you heat the same metal?
It's basically bismuth rust, not contamination.
very nice job. but what would happen if you let the bismut cool with a magnet in close proximity.
Thats really quality science and skill you're showing here. Thank you !! :-)
Cool video, thanks for posting!
love this. ill be making this
Haven't got to it. but its still on my list.
Im inspierd! I haved order 3 pounds of bismuth from the US now =)
I once saw a cube in the sky that looked very much like this that seemed to float and move just like this.
That’s really cool!

Generating a current in a coil slows a magnet down. That's where the energy loss is

+Mike Carrigan It would need to be a more powerful floating magnet
This is really great Science
have the cube coverd with a fur like cloth and sorrund the wood with copper, hook it up to a small l.e.d light and see.
this is art
1:19 that nail that's just like nope bye
That was very well made. Thanks :)
That was awesome. Thanks so much for sharing.
Mate that is awesome good work
hey NightHawkInLight you should do a video in how to make borax crystals but try to spice it up in your own epic way :D add stuff to it and see what looks better (just a idea)
I wonder how long that would spin in a near-perfect vacuum
Nice work!
Art pur sang!! Its verry nice!!!

Holy shit! Put this into the vacuum of space and this is a perpetual motion machine
Really cool, great vid.
What are the electrical properties of bismuth? What would happen if you were to run a current through it?
You should definitely paint that to look like a mario question block
If you put it in a vacuum chamber and spin it. Will it spin forever because there is no friction?
What if you cast bismuth with magnets inside?
Thanks for the interesting Video
I enjoy when I learn new stuff
Regards, Michael
No energy consumption? Over the course of 100 years would the magnet not lose its magnetism?
Good work look awesome mate
Oh my god... I love it
so you built a perpetual motion machine.. ;)
Have you thought about using a bigger one and than putting copper around it than spinning it and gaining power , does it keep spinning?
What about servo assisted mag Lev?
Using just magnets and extremely fast servos and gyros I think it could hold aloft a magnet by oscillating between being too close and too far.
this is awesome!
Fantastic!
This the shit that Coral Castles dude was onto before he died...
could it be accomplished with a bigger gap between the bismuth?
That’s awesome!
Awesome.do more!!!! Something bigger.instead of a square make a tripped out shape or a ballerina or some shit... hella cool
very interesting
Really nice video :)
So could the effect of bismuth be enhanced the same way a magnet can through electricity? Like an electromagnet in reverse?
Very Nice..
SUPER VIDEO
how thin can you make the bismuth for this to work?
also have you tried this with fluid magnet ?
I build aircraft models and thinking of integrating (a) magnet(s) into the aircraft and make it floating, do you think it's possible?
how to stop sculptures cracking over time, when they get old there very brittle.
nice short, that's how to do it
Pyrolitic Carbon Has a stronger Diamagnetic property and is much cheaper.
If you like... supercooled bismuth, would this be possible to do without the big magnet?
nice hob amazing machine
well i'd say now were in bismuth
eheheh steven universe reference
