How to make cool magnetic floating / levitating table from steel and chains.
I wonder if you could replace those chains with monofilament fishing line - make it look like there's just a magnet
Yeah. Just that you'll have to test then to make sure they can handle the constant pressure without stretching.
Yep, this setup works via tension.
The fishing line might be more difficult to adjust.

"They have made a mistake and are now trying to fix it with Grindr", yeah, you've just summarised my love life 😭😭
Use stronger magnets to hold more real weight.
The concept is really cool.
Thanks for such video 👍👍👍
There is a theorem in physics (and that is proven) that it is impossible to suspend a thing by static magnets without adding extra features like active electromagnetic stabilization, gyroscopes, strings, etc.
What's that theorem called?
@@oscarn- en.wikipedia.org/wiki/Earnshaw%27s_theorem
Is that at all or in a straight line?
Would it work if one part (upper or lower) was slightly larger so the magnetics pull slightly inward, now just down?
@@psilorder86 No configuration would be stable without external support or active stabilisation or smth like that.. That might be not obvious, people offer "solutions" all the time, but it is proven that no static magnet system can be stable supporting weight. Or in the weightlessness, for that matter.
Hold my beer...
Edit:
I'm going to make an idiot of myself now.
What if I use a tube that is closed on the end. I surround the tube with magnets, all north poles facing inside. On the bottom of the tube there is a magnet, north pole facing up. Imagine this setup like a narrow bucket with all north poles inside. Then I make a piece that fits in there, with magnets on the outside, again all north poles. I could insert this into my magnetic bucket. It would be repelled from the side and from the bottom. And gravity would keep it inside. I don't see why this should not be working. Or did I break the rules?
It would be interesting to see something similar with the magnets repelling instead of attracting each other! love your vids.
Yes, definitely do a completely levitating table with repelling magnets in the middle and supporting chains in the corners
This is really cool - it's the kind of thing I'd like to have on my desk if I didn't have a bunch of hard drives around it.
I'd love to see you guys smashing things between two big magnets. Carrots, bones, etc.
Welcome to the Magnetic Smash Channel
One major problem with this idea is that most magnets are brittle and letting stuff smash into them is going to break them pretty quickly.
When big magnets smashes they also get destroyed.
The magnet must support the weight of the top section as well as whatever is on the table. By making the top section lighter by using lighter materials the table would support more load
Now i really wanna get a set of the scary magnets and do it. The ones with a 1200 lbs pull force. Kinda terrified thinking how I'd get it assembled without losing a hand.
Collab with Brainiac75
And for today's extra content we're going to smash the evil playdoh character between two giant magnets. KAPOW! *SPLAT*
You could make a circular table and make a rail around both the top or (and) the bottom plates where you could attach the chains so that it would be possible to rotate the table
what if you mount the magnets opposite so they repell instead of attract then you dont need the big arm that holds one magnet above the other

"Grinder and paint make me the welder I ain't "
Old American proverb 😉
Lots of uses for a grinder that don't involve mistakes. Cutting material, cleaning up rust, coping pipe, making a weld flat because something needs to set on it.
A grinder and paint etc…

I really like your improvement with magnet. It is a great idea. Someone might already have mentioned it, you could make central structure more slim by using magnets in repulsive configuration. It should even deal better with increasing load as attractive configuration. On side chains use 2x4 smaller magnets per chain in attractive configuration, but alternating poles (NSNS for both up and down). Then you could make all the air gaps in the same hight and place a magazine of Anne's choice in the table gap :)
Okay, I LOVE the Fallout mug.
It's not only difficult to do it with only magnets, it's literally impossible. Look up Earnshaw's theorem. It shows that it's impossible to balance static magnetic fields by themselves. You would need a chain, or alternatively you would need to use dynamic stabilisation with e.g. a CPU and changing fields.
You can't ballance magnet like that, sadly. But you could try making something like a halfback array modified to see if you can produce a magnetic "tongue and groove" system.
Welding nuts with a bolt through them are so painful to do, they love to heat seize - a nice little trick is to put a little copper slip between them before you weld, stops them from seizing up!
Hi Lauri! Create device for mesuring force needed for spliting magnets. Its setup similar to this table, but magnets could be completly joined. Then you could apply force by press and mesure force needed to split magnets. You could make competition for the strongest magnets! Force needed to split two high powered magnets, if you apply it perpendicular, not sliding them can by quite big, so Im very curious about it. And also there is lots of different magnets to messure. Only difficulty is to make strong enough attachments, but I belive in your engineering skills. Then you can also build and use electromagnetic devices, to compare, what is stronger : solid state magnet or electromagnet? Good Luck!
Remember, you asked for this.
What I Would Do to the existing table:
Remove the extra support (you did one, do both)
Extend (or replace with longer) the magnet holders so the rod goes through the pipe, not nuts welded to them for a cleaner look.
On the base, ream the bottom holes larger so the nuts are inside. Obviously the eye bolts would need to be shorter. Once adjusted and the structure finished (see below) felt pads can cover the holes as feet.
Clean and finish the structure. Raw steel has an industrial appeal, but a powder coating would make it appropriate for household use. Chains could be used as-is or maybe plated. Same for the adjustment rods. Those same rods could be machined smooth for most of their length, leaving just enough thread for the needed adjustments. (Or you could use plain rods and machine enough thread. Whatever)
You now have a floating table you can put in your house as a curiosity or even auction for charity.
Nice. It is a great way to isolate vibrations from sensitive equipment. Some scientific experiments use similar methods.
Great idea!!!! That’s so cool I want to make one now
I made one of these out of ice cream sticks, cotton thread and hot glue for my grandson, it's amazing how strong the thing is.
Use a plastic sleeve cylinder on the magnet to hold it in alignment but use the force of the magnets to push apart from each other
hello thanks for your amazing videos. You could try to create an apparatus wich can mesure the force between two huge neodynium magnets getting progressivly closer until they stick together.
This is actually a very interesting idea, but all you’d find out is how the magnetic flux becomes stronger as you get closer to the magnets.
this concept is so cool
Use something almost invisible like fishing line instead of the chains. And measure how it can hold, with weights on top or something. Cool project!
you should totally keep that around as a conversation piece haha! maybe make a new frame with no grinding involved 😁
I'm thinking it would be impossible to replace the chains with magnets too because if they come closer to connecting, the middle one separates more and they would be in an anti-equilibrium
Great, Like a tensegrity but magnetic :o
Change the chains to thin fishing line and use thiner steel bars.
Nice project! I would suggest that you build the table using repelling force. It could allow a more clean and streamlined layout.
Hi Lauri -- I wonder if an all magnetic model would work if each remaining "chain" were made from two sets of opposing magnets each on a frame and the magnet sets were carefully chosen such that the pull up magnet set could be defeated by a smaller yet stronger magnet set that would repel as it got too close together.
[ or maybe three small powerful opposing magnets surrounding the inner large pull together magnet ]
The idea is you need some sort of self correcting feedback mechanism to replace the remaining chains in such a way that the a small perturbation doesn't unbalance the forces.
Such a design also probably calls for some posts (or whatever) around the table top with opposing magnets on the table top that keep the tabletop from sliding sideways.
I think the lighter you could make such a design would also make it easier to execute (especially for a prototype).
This is honestly a fairly neat idea and a good iteration of the "tensegrity" hype. Putting it in inverse and making a magnet repulsion compressegrity structure?
Nice work Lauri, looks pretty cool!
Electromagnets and a distance sensor between them. If the distance increases, the power to the electromagnets increases, increasing the load-bearing capacity of the table and vice versa
Should’ve put both magnets in a plastic sleeve cylinder so that the magnets would have something to brush up against and hold it study and straight but use the force of the magnets to oppose the force
Love the coffee mug. More a Nuka-Grape fan myself.
I've been binge watching beyond the press videos for the past two days and was thinking... when will there be a new video? 🤔
Now... is the answer.
Make it bigger, like a bigger coffee table for your lounge room. use large Neodium magnets with a larger gap between, Then you cane use a hydraulic press to see how much weight it takes to break the magnetic force.
Imagine: two tables, magnets on all 4 feet of both, same poles facing each other. Set them up so that the feet of one sit directly over the feet of the other, and use maybe some kind of clear plastic cylinder to keep them lined up. You now have a levitating table based on magnetic repulsion.
5 trasparent tubes to channel 4 corner (4x4 same pole magnets) and 1 center (N+S magnets)
Hi Lauri! Maybe you can make a special tube or other holding device and then try to make close or even contact magnets turned to the repeling sides ? You can use press and messure force. Some Neodymium magnets can be really strong. You can also make 4 tubes from non-magnetic material (like a telescopic) place inside repeling magnets and create magnetic suspension ... table? or comfortable chair?
And the end with the coffee cup tagged nuka cola makes me want to play some fallout
Could you use 2 magnets or more to repell each other? Then you can make a gap bigger and not worry if anyone leans over it as it will just spring back up
Electromagnets - switch them on & the 'table' stands up - but only as long as you pedal fast enough : )
We needed the table overload test 😎
Try strong thin fishing line instead of chain. It would improve the illusion. : )
„grinder and paint, make me the welder I ain‘t“
I want to see how much weight the table could support if you used the strongest magnets possible and left only a millimeter space between the top and bottom magnet.
"Application of grinder and paint
Makes me look like the welder I ain't..." -- welding instructor, ages ago.
I bet you can make it all from magnets, stabilizing the movement from all directions.
Yeah, unfortunately levitation with only magnets is never possible, it is always an unstable equilibrium, like balancing a pencil on the pin. But like you did it, it is still very nice and cool! Would’ve liked to see, how much weight it could take, until it drops.
Could you put the 8 maginets at a 45 degree angle downwards in a circle and have one or more maginet pulling in the center. Then it could be spun around
If this was your idea, great job! It's brilliant.
By the way, the 5-magnet design is actually impossible to balance.
Maybe you should do a demo on those strong magnets to see how much damage they can do. Could you do a table, that has magnets opposing each other in the 4 corners, and a larger magnets in the middle opposing each other. Might be hard to keep it lined up though.
I love the floating tables
Because of the magnets attraction to metal and not making contact to actually float. Could you use clear acylic as a spacer between all the magnets and then use a clear acrylic tube as support on the outside of both magnets like a shock tube supports the plunger inside of it.
what if you were to use two small magnets attracting one another inside of a piece of plastic tubing, each superglued to a section of chain- and use this levitation for each of the four arms?
You might be able to do it with just magnets by using superconductors, or for more of a challenge dynamic control with electromagnets and an FPGA. It should be easier to figure out than Ikea furniture and who doesn't want to have to plug in their table? j/k
Make a plexiglass box for the table to sit inside and you will be able to use just magnets because you won"t have to balance anything
A large version of this would be a cool coffee table or bed stand
If you use two magnets configured to repulse each other then you don't have to loop around. Also it would just gradually sink down with increasing load instead of having a fail limit where it suddenly falls down 🤔👍
It would look cooler with as light of Chain as possible. Ball chain?
maybe the strength all the four magnets together at the bottom need to add up to the middle one. one 100k in the middle and four 25k on the bottom
Nice table, it complements the mug 👍👍
if you use fishing line instead of chains it will look "invisible" and like it's actually floating
Why don't you make them electromagnetic then you can turn the power up and get more distance between the magnets and you might be able to get that under the press and see just how much weight it could take. Brilliant show again guys. Please take care and stay safe
You should use very thin cable for stabilizer
I think I'll make one of those with the magnet for myself, that is pretty interesting.
instead of the two magnets pulling each other together make a table where the magnets would repel each other so that heavy load would push them closer
man I could listen to lauri explain literally anything in his janky english. It's got this weird musical quality to it
Magnates objectively make everything cooler. If I could incorporate them into love making....
Transparent tubes with magnets..? Or .. glide rails ..? .. Magnetic engines..? Perpetual Mobile..? Angular opposed magnets on a wheel..? Cones on top of each other, floating, spinning..?
You could make it work with magnets through quantum locking but it only lasts a few minutes unless you have a way to keep your magnet at about 100 degrees c below zero.
Make an electromagnet, that way it can be stronger, but also it can be turned on/off while you fine tune the positioning.
5:42 lmao I miss Annie and her expressions... but here she is in the background
This table would be perfect for people who live in Japan or California and don't want to spill their coffee if a small earthquake happens.
Use smaller neodymium magnets to make the gap way bigger!
Used plastic sleeves on all four corners with magnets
How come Anni isn’t on Instagram anymore? A lot of her stuff was hilarious and fun.
She hasn't been on camera much lately either, or blogging on her channel. Not really sure what's happening?
Pregnant. Just wait for the announcement video.
Some kind of update would be great, just to hear that everything is ok, my imagination is running too wild :D
No extra content with her clay animals either...
I been wondering the same, hoping she's ok
Non ferrous for every component not the magnets of death, maybe copper would look sweet, or anodized aluminium.
Kaikki nurkat magneeteilla onnistuu kyllä mutta siinä pitää hieman käyttää päätä enemmän. ja joko nurkat vetää toisiaan puoleen ja keskellä hylkivät magneetit pitämässä korkeutta, tai sitten toisinpäin että nurkat hylkii ja pitää korkeuden, ja keskellä puoleensavetävät magneetit mitkä keskittää kokoajan systeemiä. Helpotusta voi tuoda tekemällä 45° kulmia. Nämä vaan tälleen sekunnissa päässä mietittynä... ;)
Thank you! Inspiration!!
How is Finland different from Heaven? Heaven has no electric sockets to run power tools.
What a great concept! Thanks! Dave J
Here is my improvement. Replace the big chains with very small wires or string. This way it looks weaker than it is. :-)
Iam sure it can be really well detail on my table if its lighter.
I'm curious what this would be like in a moving vehicle
Like this "workshop" content, very nice.
You either need to be good at welding, or good at grinding.
Would probably be more stable if you made the bottom frame bigger than the top.
really interesting video again
love it
What if you used aluminum instead of Steel? My immediate thought was get eight strong magnets and put in each Corner of the top and bottom opposing each other. Then use some small, preferably non-magnetic, cables to basically keep the top-of-the-table from the flying away. I wonder if you could arrange the magnets in such a way that it would be stable?
Love that Nuka cola cup ❤️
I mean you could also use rope as well he didn’t need to use chain
I like it! Very cool!
isnt it weird that you can look at a welder in a video and be fine but in real life it will burn out your eyeballs 😂
You need to make one with big 2 ton industrial magnet for lifting plates and stuff
Now THAT'S how you lose fingers. Lol
