- PLEASE RATE THIS VIDEO - COMMENTS ARE WELCOME.
Here I present a suspension device in which a neodym magnetic sphere levitates. The electronics are in the pedestal and on top is an electromagnet with sensor (SS495A). The voltage supply comes from an external power supply unit with 15V direct current.
Gracias a un ajuste preciso, la esfera queda suspendida en el aire.
Dank raffinierter Regelung wird die Kugel in der Schwebe gehalten.

loved the style of the structure... and i love floating thing in general too, its quite magic
Echt cooles Teil, da steckt ne menge Arbeit drin, aber die hat sich gelohnt.
LOL everyone except you were props watching magnet vids before this. Damn man.
Love this stuff
@Elrumel
absolutely, a perfect idea! The levitating car key.
FREAGGIN LOVE IT BROSJ! a warm helping hand for my new development, thanks to this prosject. Thank you so much for sharing!
OneLove
Very helpful, thank you!
Quader schweben auch!
Sehr gut!
WOW SO NICE !
That's fantastic
are u feel like a king with this simple video?
Interesting.
Congrats.
There's a sensor in the base which adjusts the electromagnetic field as the magnet moves, keeping it fairly stable. Very easy to knock out of balance, though. Pretty much any movement that knocks it out of the exact center causes the magnet to fall or stick to the base. I had a friend many years ago who had a small globe that worked similarly. It was quite fascinating.
@NewtonBlog It's wonderful, thanks!
@Scrumplesplunge You can believe it. The magnetic sphere hangs on the magnetic field and it behaves exactly the same like a ball on a string. Amazing but true!
@50Papst
Ein Elektromagnet (Spule) wird eingeschaltet. Es wird der Schwebemagnet angezogen. Nähert sich die Kugel dem Magnetsensor (Hallsensor in der Kuppel), so reagiert dieser und schaltet den Elektromagneten wieder aus. In der Folge sinkt die Kugel wieder ab. Der Magnetsensor schaltet in diesem Moment erneut den Elektromagneten ein und der Vorgang beginnt von vorne. Dies geschieht ca. 70mal in der Sekunde.
There needs to be a smooth 1920s narrative in the background with this music. Something about a rainy night and a girl running into a bus station just as you look up from lighting a cigarette and your eyes meet, for what seems to be a lifetime...
Hallo Andreas, das ist einfach super. Meine Anerkennung ist dir gewiß. Gruß

That is an amazing wooden table.
@gocartsgo It would. The poles would be generating constant resistance and it would eventually come to a rest with the poles aligned.
Very cool👍👍
Stable magnetic levitation is only possible in 2 dimensions in a passive system. The third dimension needs some form of stabilisation - such as mechanical connection or contact. In this case, the third dimension is stabilised by electronic control of the magnetic field in that direction (up-down).
This type of design is very common in magnetically levitating toys and also in magnetic bearings for special machinery.
This is so WOW!!!
does it stand where you leave it or is there a "balance point" where it will be dragged into if it is in the field's range?
I get it one magnet on top is plus and the other one minus awesome dude
@alexb1k3r You don't need a magnet on the bottom. Gravity does the "pulling" to the bottom. I would say the sensor detects the magnetic field strength and the electromagnet current is switched on and off quite quickly. I would imagine that the sphere is rising and falling very quickly by only a few microns.
If you spun one of these in a vacuum chamber would it spin forever?
@sagazbrutal not this in particular, but maglev trains, particle accelerators, plasma bottles, and VASIMR rockets all use these principles.
Are you using transistors? I build similar device but can’t get that distance
I want this as a decoration :D
wow Nice work
So is it built up momentum from being touched, and the magnetic fields putting resistance on it's spin?
Very nice man!!! Are you using a PWM signal to switch an electromagnet?
@xSaDii Thank you Claus.
There are some but the most are clever!
If you:
1) grind down one side of the bearing just enough to get a flat surface, then
2) use a pencil to hold the flat area in place at a right angle to the magnet, then
3) Spray air over the top of the bearing to spin it
Than should give you precession when you let go of the pencil.
I did something similar in a post graduate physics lab to measure gravity (with a strobe light to measure spin rate and a laser to measure precession).
The precession can vary depending upon the spin up.
It's a magnet in the top, making a field just powerful and large enough to support the ball at that position. The magnetic pull is just as strong as the gravity pull, making the ball hover.
very nice ,impressive :)
thats pretty cool but will it blend?
so i am guessing that it counts the objects weight with that sensor it has so that it gives enough electrism to keep it in that exact height...
I'm sure this is done with an AC magnetic field. The AC field induces currents into the sphere that try to prevent the magnetic field from penetrating the sphere. But, it looks like an iron sphere, which also is attracted to the magnetic source. The current in the sphere also has a momentum, which is another way of saying the sphere has inductance. So it is complicate to design or predict, but not impossible to occur.
Way back high school physics, this was my project. The only thing that failed was we were not able to buy the right sensor that will limit/produce the right ohms (dunno the correct term for it) that will stabilize any metal being suspended. I am really obsessed with magnetism.
No, the field constantly adjusts itself to balance out the floating object
nice idea
beautiful
I was wondering, if you put that ball to spin, how long it would have a motion before in stops?
How many small ball bearings could it support? Also, what would happen if you put iron filings in it?
Cool, wish i could get me one of these
amazing !
@bryceguy72 Thanks for the compliment!
Any idea what causes the metal objects to spin in that manner when in suspension?
you should attach something to the ball ^^
or cover it in a costume!
now THAT woule have been awesome
Thank you
Top only!
If you put it in a vacuum and spin it, will it spin forever?
I had this idea to do for perpetuum mobile, to put a ball surrounded by magnets, get all the air out and spin it.
this is real. had them as a jid and are still sold in hobby stores today.
@ANTHMX I know, right? Because nobody from any other country ever does that, do they?
@bis0uhr warum nimmste nicht einfach permanentneodymmagnete und machst das ganze ohne strom ?
@Aaronlime1 the question is do we know enough about magnetic fields and its effects on bio-cells. Remember it took us a lot of time to figure out the effects of x rays.
This is must a be a future car idea
@thepeoplesamaricuh 1) "flux fields" can't collapse unless your referring to electromagnets (they get compressed). 2) twin electromagnets of radius equal to spacing creates a magnetic well of minimal potential where the magnet likes to stay. It requires energy to move the magnet from the spot, thus giving the swinging motion when his finger pushed it. It is exactly the same as with string.
Why do the blocks change rotational direction? This is a clever camera trick if you ask me.
Of course :-)
@BranVel The music is by light2art.de
dude u found the future of floating cars
@jokerfacehro
Doch - Levitation mit Dauermagneten funktioniert, jedoch unter anderen Voraussetzungen.
hummmmm por lo visto no haz explorado mas a fondo esta tecnología
@MendocinoManni Danke, wo treibst du dich denn überall herum?
Yes, it is.
theoretically, yes. so long as there is no force of friction of other forces acting on it then it would just keep going
this design is so trekki!
I want one of these on my desk!!
could u show me how to make this ? ?plz .its amazing :D
Of course.
where do you get the tool to make magnetism ?
Thanks
How do you make this? (or buy it)
I tried the project site, but google was having a hard time translating the German. I suppose I could individually copy the text paragraphs, but that would be arduous. Are there any english tutorials? And is it possible for a complete amateur to make one?
whats the difference if you put it outdoor?
if you move the device-does the object inside move together with it?
Is there any place in which I could purchase one of these fine contraptions?
Can you put neodynium magnets in the center to levitate?
Is it very high pulse intesitivity modulation?
Does it require certain weight for the object?
Cool.
Will it blend?
respect
i would love to see you connect battery terminals to the sphere through brush contacts and turn it into a levitating homopolar motor...
@bis0uhr achso ok, gute arbeit ;)
@Scrumplesplunge The ball orients itself to the north & south magnetic poles & rotates only on this axis
Believe it
hi my friend!! Great video.. please can U explain, how it does?? grteetings from EC.
Tks.
could you show me your diagram? i try to do one like this but i can´t and i want know how you conect the elements in this case. plis help, thank i hope your answer
www.supermagnete.de/eng/Magnet-applications/Floating-sphere-Levitron
How can I calculate the magneto in the coil for more diameter (11cm) and wight and how much voltage I need to make it works????
sehr schön aber wie funktioniert das ?
@Zdegrey yeah right it's obviously a string.
the magnetic flux field would have collapsed under that much stress, ergo, the string.
Das ist Wüderbar!
love it.:) can you share plans. if not i understand :)
Yes, once again, I know how the circuit works. My point was to show what a complex circuit is required for a stable levitron. There is another MIT design which is the same as the toy circuit here. Can you please just answer the simple question I posed earlier?
which the necessary energy to levitate this sphere
Awesome levitation - Anyone know if you could do this with a standard Neodymium Magnet (non electronic) and if so how large would the magnet need to be to to support a small 10mm sphere magnet (as shown in this video)?
Understand sphere magnet can pull with over a kg of force, but is the sphere quite heavy itself?
thanks
Unless you figure out how to control your permanent magent, no you cant. The system relies on electronics, that check the sensor that says how high the object is, decrease the current in the coil if the object is too high or increase it if the object is too low. If you just have a permanent magnet and a object that is not a stable system, the permanent magnet does exactly the opposite of this control system, closer the object is more force there is and vice versa. So your object will eighter fall off or fly up and get stuck, it will not float.
I understand thank you very much for explaining the details to me - I was originally thinking along the lines of if you had a permanent magnet, made with the exact magnetic force as an opposing gravitational force on an object - So could this still work on a mechanics diagram...just really impractical in real life to create a functional model....? - Appreciate your wisdom :)
