as a wise man once said:
"magnets are just wireless legos on atomic level"
Old Honest Abe knew a thing or two
@@worldcomicsreview354 hmm
That man was Wisebert Wisenstein
If he was actualy wise he would have said lego and not legos
Could an aerodynamic Lego set survive a gliding fall from the stratosphere with a Go-Pro and GPS connected to it or would the high winds demolish it before it hit the ground?
Nice question...
Depends if this is a technic set or a normal lego set…
I doubt the wind would break it if you made it stable enough
Matbe, but that would require some very talented lego builder to design it strong and wind-proof enough
@@NoNo-rj2hl why would that matter? Standard Lego is incredibly robust when implementing brackets into the build. Watch the bridge episode on the first American season of LEGO Masters.
That color grading at the end was pretty phenomenal
It might be interesting to see how much power could be transferred in this way.
A lot. Some pumps work this way. They are designed like this because they pump hazardous chemicals and this way you don't need a rotating seal around the shaft. No chance of leaks this way.
The only problem is that it likely has about 0 torque.
I can prove some insight here - I work with and maintain rotary vane pumps in a laboratory and a lot of our pumps are "magnetically coupled" pretty much in the way demonstrated here.
How much torque can they transfer? A lot - those pumps usually run on fixed frequency AC motors with only two speed settings also called "on" and "off"
Whats the advantage of this coupling? Little to no maintenance and the most important thing - waaaaay less chance of oil leaking. You can change the motor of a pump without draining a single drop of oil within 2 minutes.
@@minklmank not exactly those pumps are just permanent magnet motors, and generally dont need a heap of torque since there is little resistance when starting since centrifugal force is what moves the fluids which relies more on the motors speed which is also another reason they are good for pumps because if some foreign goes inside it, it can lock up the rotor and there is a less chance of damage
@@minklmank The fact you work on these pumps and yet don't realize how they actually work, is worrying. Inverse square law...
An extended video of the slow motion capture of them at high rpm would be awesome to see
Great video! Love the concepts and ideas used through the thinking process!

*Pls just kill me already*
This is actually the exact method by which Qi wireless phone chargers work. The only difference is that it's electricity moving in circles instead of physical magnets.
Brick experiment did this with he’s submarine. Nonetheless great job
Yea
his' *
I saw that vid
@@mauntaxthelegend3188 you don’t need the apostrophe for pronouns because ownership is assumed
@@pieppy6058 right xd
it would be fun if lego made magnetic lego pieces
I actually own a lego magnet piece somewhere in all of my stuff
They did - railway car connectors from at last one lego train set i had in the 80s
(not sure if its true) There were magnet pieces in old venator class star destroyer from star wars
I agree,they need to make a magnetic piece like a crane with power function,just like magnets crane used in junk yard
There was a whole line called Magnetrons
Very good job!
A shaft is wireless energy too
Be careful if it spins too fast it might LEGO
I’ll see myself out
Your channel is just gold, pure gold.
Thanks!
It seems a useful system although if they have a certain separation they would be limited to systems with little workload, although if the Friction powered systems like the mini submarine could be delivered.
It's really cool that lego's can even emulate brushless motors in a sense
You could make a very cool GBC module with this
This is called a Halbach coupler for anyone who wants to learn more. very cool and useful for industrial applications. Nice project!
To me, it just sounds like a clutch
@@nefarioulyte9996 a clutch is a device to disengage and engage power. This could function as a clutch, but the fundamental device is called a halbach coupler and uses alternating polarity magnets to couple rotations without a physical connection. Seriously, it is fascinating and worth a google search
This is basically how a synchronous motor works.
I’m telling.
0:42 woah the soundtrack for the new Dune film is really impressive
This would be really useful for sort of art pieces or decorative mechanisms
Cool idea!
This reminds me of how I write my essays. Trying to describe the most simple thing in the most complicated way
I did not expect that much rotational energy to transfer!
you do relise
that the torque output of that is basicly nothing?
"rotational energy" you mean rpm? cause if you jam it to 1000rpm quickly then it wont work
if you slowly get it up to speed then it works but it still aint got shoot for torque
@@djaydeved it'll probably work when kranking it up instantly (up to a certain rpm at least deoending on how strong the magnets are) but it would "drag" in the beginning.
Very cool how you combine normal objects with Lego !! I like ur build I mostly want to make builds like that too but don’t have the bricks for it 😂
Wonder if something like this could be used for a torque converter. Not sure the advantages or disadvantages though. But It could be cool to see done.
thats the same thing I was thinking too lol
Direct coupling of magnets like this is inefficient, but it's not too far removed from an electric motor. You'd be better off with a generator and motor set, in which case it's already known as a diesel-electric drive train used in diesel locomotives and heavy vehicles. It's also the basis for some Hybrid EVs which may or may not use diesel, but that's not the important part.
Doing it this way, rather than using shafts, allows for much more freedom in where you put the power unit, and where the driven wheels are, and how those wheels can move. It also allows for exotic, power units, such as turbines without needing a complex gearbox, or a mixture of power units that can all feed the same motor.
@@kal9001 so it’s more efficient to effectively just use the engine as a generator to power and electric motor?
What about using magnets in combination with a regular torque converter? Could it maybe help the input and output sync better?
@@kal9001 That's a completely different thing. Do you know what a torque converter is?
Great engineering! Nice touch with that music and smoke in the end.
Thanks! Glad you like it 😊
This is wicked, also what did you record with? footage so crisp
Very interesting!!!
If u made car on this method, i be in shock
The end was absolutely epic
Great engineering and Video cut
Thank you!
Mr. lego: "I'm very dizzy and nauseous"
So satisfying to watch.. I already subscribed
You do not stop to amaze me
If beltless CVT existed.
Is it just me or is the lego motor singing hamburger cheeseburger bigmac whopper in the RIGHT VOICE
Lego man: I didnt sign up for this
0:37 I wonder if this principle could be used as a torque converter.
It's way less efficient... Also it's irregular
That would be a horrible idea. The amount of energy lost between each magnet will follow the inverse square law..
Excellent!
Idea: make an automatic race car that when it goes a bit too fast its engine explodes / hood pops up quick and parts fly out.
2:41 this is just a magnetic field generator now
My son (4) and me loves to watch your Videos!!!
Wow, thanks
it's basically a magnetic torque converter thats pretty cool
oh my god what the heck that is so cool
Spaceship! Spaceship!
Really cool concept, Shame the torque will be almost non existent
Make a saw movie contraption haha
Humburguer, cheeseburger, big Mac Whopper!!!!!
Das ist das Grundprinzip einer magnetkuplung wird so in den meisten wasserzählern verwendet damit sie keine wellendichtung brauchen und über ihre Laufzeit wartungsfrei bleiben
The weight constriction can still slow down the motor
PUT THIS MAN IN HARVARD DAMNIT
It's like a magnetic clutch
where do i buy these types of lego ?
Интересный подход 👍
honestly wondering where to get all those neo dimimimimiminum magnets
Idk why but the engineer in me is super happy after watching this, and also the scientist too lol
Happy for the both of you! 😉
Nobody ever said it couldn’t be done!
The Six Million Dollar Lego Man.
Magnets are basically magic, no one really knows why any of this happens (sure they can describe what happens, but not why), which is why I love it.
The end 😍💙
You've just visualized the basic workings of an AC motor!
I'm never going to be the same again.
I'm actually wondering how much rpm difference there is between the motor and the lego man...
My theory is that this works like a synchronous motor, so the RPM would be the same but there would be some phase difference, depending on torque. Too much torque and they de-synchronize, at which point significantly less power would be transmitted as the driving wheel would spend (worst case) half the time accelerating and half the time decelerating the driven wheel.
There's zero difference.
same rpm by the looks of the slomo but torque transferred is only a fraction of the motor
“Wireless energy” a better explanation is magnetic motion transfer
this is cool
It's called magnetic coupling
😬👌
the most powerful concentration of magnetic force in the poles of the magnet (large accuracy. from the side of the magnet, these forces are dispersed in space and are many times weaker). Therefore, it is necessary to place the magnets with poles to each other for the greatest possible adhesion.
Thank you for the nice suggestion!
Run a wire between the magnets to generate electricity.
I know I will probably get a "because i/we/they can" answer but What use case would something like this have?
Now that's attractive.
without having seen the video: Yes of course it is possible, why would not it?
Why did you remove the walls? That was the entire point!
Hello: D new follower: D is that I already like lego and I was watching videos and I liked lego technic and I wonder where you bought it, I want everything xd if you want you can send a link plis: 'v
Try bricklink com plz
Awesome video is this could be' considered "wireless energy"?
Sure 😊
As awesome as it sounds, there aren't a lot of applications for it because anything would create a load. If it was for circulating air or something that can work.
@@ethanoldenburg6645 lol there are a LOT of applications for this and it's used in reallife. Starting with motors, pumps etc.
that so cool
Yees....more engineering with lego! Just what i need
Awesome!
Thanks!
nice vid
Glad you like it!
now do an alternator
It isn't really practical as the magnets would just shift around (like a cutch gear) if the load is too heavy, and little motion would be transferred.
btw the editing is good
Самый гениальный гений:
Try to make electromagnets using lego
Cool enough!
wire, is more common shaft
How does magnets work?
How i get that lego?
nice, but no torque
Love u brohh. From india🇮🇳🇮🇳
Thanks!
Very good
Thanks!
There is a wierd amount of sound in this video
Here comes the CIA
I always wonder why this concept isnt used much in the real world.
Surely it would make a massive difference in engineering, making it easier to have sealed systems etc
Huge amounts of energy loss due to friction so it isn’t very efficient
When it’s needed this type of thing is used, it’s just that there is more energy loss with this than a shaft, and sealing holes is not that hard.
The greatest loss is due to the inverse square law. The loss of energy due to friction is almost negligible compared to it.
@@bad_request5088 I’m not familiar with that law haha. What does it mean?
What about the torque?
no, the magnets will slip.
big dune vibes
like the sound
That's cool😎 (🇧🇷)
What dimensions are those magnets?
Are the ferite or neodym magnets?
Neodymium
@@DrEngine I saw neodym magnets 4x2mm, they should fit the LEGO holes
So you are using bigger ones?
I heard they are fragile, it that true at this scale, or are they small and tough enough?
@@jakubpollak2067 I used 8*3, and yes, they're very fragile, broke 3 or 4
@@DrEngine Thanks for feedback
I'm planning on making a plastic capsule around them with 3D printer, simple hollow cylinder and put them in just before printer will make top to enclose them
Hopefully it will secure them
Also the "capsule" should have LEGO holes and pins
Are you interested?
@@DrEngine How? They're IRON, and shouldn't be fragile at all!
Это гениальноооо!!
Are those neodymium magnets?
💯
a magnetic zero contact clutch
interesting
Why the L-Motor sound buzzy?
