It is cool ! Congratulation.
Thank you.
Very well done. What is fun is that the top can be made with 4 magnets as well.
Thank you for your comment.
Very nice
Thank you for your comment.
あと、真ん中で回るけど、10秒ほどで、止まってしまいます。動画のように長く回すにはどうしたらいいでしょうか。ｺﾏの問題でしょうか。そこも教えてください。回答お願いします。
OK, thank you so much,1 for showing to use clear film instead of strings to stabilize my magnets above a magnetic field(much better, 2 let's place these magnets in a parabolic shape convex and concave, and see if with said Natural focusing ability to see if this might form a better field where the magnet(top) levitates with hopefully no need for the field stabilization that spinning provides, 3 I would love to see your top spinning over a copper plate, and a copper parabolic shapes too. thank you for sharing... it was great help and proved I am on a viable course to m goals...
Thank you for your comment. I don't think it will surface on a copper plate.
Muy bueno el video saludos amigo Daniel
Thank you for your comment.
Wonderful project which I will attempt to do. Can I ask you whether the polarity of the 4 base magnet are all North or South, and the spinning magnet, is it the opposite then the base ones?
The polarities of all four base magnets are north or south. Either one is fine. And the polarity of the rotating magnet needs to be in a direction that repels that of the base.
How long did it take for u to levitate the magnet top? Im planning to do this for a school project but im afraid it might take some time to work
It took about a week at first, but once I succeeded, the tops began to surface in about 30 minutes. It's easy to float once you know how to do it.
Instead of starting a school project from scratch, do it yourself.
I think the next video is better than this video for adjustment.

What's that thing that floats in the air?,where can I get it?, Thanks for the awesome video btw :).
I think that it is floating by the repulsive power of the magnet and the gyro effect of spinning top.

1ダンボールの紙の縦、横の長さはどれくらいですか？
2この動画の作り方と、もう一個(二の方)の作り方は、どちらの方が簡単、成功率、が高いですか？(オススメの方で)
ボール紙の縦横はとも90mmです
作りやすさはⅠの方ですが、成功率や調整のしやすさはⅡの方です。
私は”空中浮遊ゴマの作り方Ⅱ”の方をおすすめします。
Me gusto la presentación al igual la guía para copiar su confección, lo intentare en próximos días.
Gracias por tu comentario.
Truly amazing!!!
Thank you for your comment.
@@yattemita4447 Im so impressed, Im going to have a go at making one!
Please try it.
Where exactly do I need to put the circles on the board? And where did you get your supplies at?
The four magnets are arranged to inscribe a circle with a diameter of 82 mm.
I bought at 100 yen shop(Dollar Store).
理屈は理解してても、実際に目にするとスゴイね。
コメントありがとうございます。
初めて浮き上がった時は感動しました。
Hello, I'd like to answer two questions.
The first is the size of the plastic box used or the distance between the 13mm magnets.
Another question is what material you used to make the central pin on the 13mm magnet.
Thank you!
Thank you for visiting.
The dimensions of the case are 9 cm in length and width.
The distance between 13mm magnets is about 5cm.
The central pin was made with bamboo chopsticks.
Lovely 👏👏👏👏
Thank you for your comment.
Please Sir how did you make the last 23mm neodymium magnet with the chopstick ?Did you Drill the center of the neodymium magnet before inserting the chopstick and then applying the hot glue around it to keep it in equilibrium in spinning?
There is no hole in the magnet.
The chopstick is bonded to both sides of the magnet with epoxy adhesive.
Hello! nice device you've made. Is it possible for you to write how strong (in kg) the magnets are? thanks.
I do not know the strong (in kg), but the magnet with a diameter of 23 mm has a magnetic flux density of 140 mT.
Hi great work . how time can it be in livitation or in spining . thanks .
It is about 1 minute.
Thank you for your comment.
MEU AMIGO , POR FAVOR QUAL SERIA A ESPESSURA DOS MAGNETIC DE 13MM E 23MM ? GRATO , FICO NO AGUARDO , LINCOLN BRAZIL .
Ambos os ímãs têm cerca de 2 mm.
Hi, what is the separation between magnets? Nice video
Or the radius of the circumference that contsins all 4 od them
The radius including 4 magnets is 41 mm.
Any recommendation for the destination in between with diameters of 15mmx2mm and 25x3mm neodymium magnets?
There are no recommendations.
Please think while actually making.
yattemita３２５ Finally make it after couple of days adjustment. Thanks for your inspiration. th-cam.com/video/OsAs4cLwrIA/w-d-xo.html
Can it carry 500 gr item? And can it lift more higher? How to add its power and high? I wanna make it by myself, dont want waste 100$ on eBay.
Even 1 gr item can not be carried. It is the limit that floats of 8 gr top. Height can not be changed. I do not know how to add power and height. I think you better not make it yourself.
WOW WOW WOW increíble me encantó lo voy a intentar vale la pena gastar dinero en estos materiales 😝👌👌😆😁😀
Me gustaría que hagan más vídeos así !!!😝😁😀👌😎👍
Thank you for your comment.
Nice how much time it stay in runing possion. Pl.reply
It is about 1 minute.
Que lindo ❤
Thank you for your comment.
What are the independent and dependent variables to this.
I do not understand
! Asombroso ! tu experimento, en apariencia simple, resume miles de años del acervo del conocimiento humano. La simplesa y elegancia de la presentación te merecieron un "like" pero sobre todo mi reconocimiento por tu ingenio y capacidad de síntesis para resolver problemas. Felicitaciones.

Y Benito juares fue un estúpido
How did you stick the chopsticks perfectly in the middle of the magnet
nice video :)
I used the Circle Center Finder to find the center of the magnet.

Thank you. Can i also use a ring magnet 20*3 mm
I am sorry, but I do not know because I have never used a ring magnet.
No problem
wow good
Thank you for your comment.
What is the thickness of the magnets?
Will it help if I get thicker magnets?
Will it work if I use only the 23 mm magnets?
This is the only video which utilises such low amount of magnets. Great work bruv.
The thickness of the magnet is 2mm.
I think that even thicker is possible.
I think that a 23mm magnet can be used instead of a 13mm magnet.
However, I think that the arrangement of the six magnets must be adjusted in various ways.
Are those N35 magnets?
N35 I don't know if it's a magnet.
I’m sorry I didn’t get you.
Are those N35 Neodymium magnets?
I don't know if it's a N35 magnet.
Can i use the 8 magnets with the same size? is it going to work having same sizes? thank you very much, i liked your video:)
I do not make it with 8 magnets so I can not say whether I can not do it.
In the case of 6 magnets it works.
Therefore, I think there is a possibility that it will work also in case of 8 pieces.
However, I do not know if it is the same size or not.
Thank you for watching.
thank you:)

お聞きしたいのですが、４つの２３mm磁石の上で後から調節する１３mm磁石ですが、少し大きめの１６mmでも問題は無いでしょうか？
また、安定して回転するコマはどのように作られたのでしょうか？
こればかりは、やってみないと何とも言えません。この動画では、たまたま13mmの磁石があったので使用しました。
コマの磁石は円盤型でその両面に丸い竹の箸を接着して作りました。磁石の中心に接着することが必要です。
お返事ありがとうございます。
参考にさせていただきますm(__)m
Can you give me perfect measurements of magnets placement , cricle and height
The four magnets are arranged to inscribe a circle with a diameter of 82 mm.
The height of the top is about 20 mm.
Good
Thank you for your comment.
Cool
Thank you for your comment.
How long does this spin for?
It is about one and a half minutes.
Interesting
Thank you for your comment.
Its necesary to spin the magnet?
It is necessary to rotate.
It will not float unless it is rotated.
What's the use of it ??
Where it can be applicable ?
This is a toy that is based on science.
Can you explain the polarity of the magnets? Were they all the same polarity? Alternating? Thanks!
They are all the same polarity.
Thank you for watching.
good
Thank you for your comment.
Can you make a levitron using a battery as a center and have it rotate on its own axis until the power of the battery is finished? Thank you

Son caros los imanes de neodimio ? y donde se consiguen? porque no en todas las tlapalerias tienen.
I bought it at a 100-yen shop. The one with a diameter of 23 mm costs 100 yen. You can also buy it on Amazon.
このコマは空中で止まる事はありますか？
空中で止まることはありません。
１分半から２分近くまでは浮いていますがそれ以上になると回転が弱まって落ちてしまいます。
ﾋﾞﾀｯｯｯｯｯん!!!!!!ってな笑笑笑笑

回転が止まると独楽の上と下がひっくりかえって落ちるんですね、恐らく。
Does the rotating part stop at any moment. if it does, after how long
About 1 minute 40 seconds.

nice magnetic top...
try use a empty and full vaccuum in a jar with top...
will top run or not

浮上したコマは何センチくらいのところで浮上していますか？
約４cmです。

question, How long does it last without be touched while it's floating?
It is about 1 minute.
Superb❤❤
Thank you for watching.
Where do we get this magnet
I bought it at a 100 yen shop.
What are the length between the four magnets and the piles of the magnet
The height of the top is about 40 mm.
Thank you for watching.
あと、動画では、回してから、上にあげても、真ん中で回り続けてますけど、自分のは、下らへんでは真ん中で回るけど、上にあげると自由にうごいて回ってしまいます。どうしたらいいですか。教えてください。13mmの磁石は、真ん中よりに置いてあります。
Hello!!
Will it works if I use magnets of 25 mm and 15 mm instead of 23 mm and 13 mm.
And if I use magnets of 25 mm and 15 mm, could I use magnets of 3 mm of thickness or maybe of 5 mm of thickness?
I do not understand. Because I have never done under those conditions.
Hello Pal!!! I did everything but the spin starts spinning perfectly stable and when I try to move it up it starts moving around in bigger circle until it falls... Any suggestions???
Try increasing or decreasing the distance between the four magnets.
Thanks... It's stable now but I keep pulling the cup up and nothing happens...
Then, narrow the four magnets little by little.
Little by little.
OK thanks!!! (the top ones, right???)👍
Probably the deck (where I start the spin) has the problem cause there is nothing I haven't tried with the base... Any ideas on how to make it;
can you please write how to make that paper board and peg top? such distances as in cm and mm measurements.
The length of the paper board is about 95 mm.
The four magnets are arranged to inscribe a circle with a diameter of 82 mm.
The shaft of the top was cut chopsticks and glued to both sides of the magnet.
@@yattemita4447 Thank you for the details!
なんでできないのかなと思っていたら、ｺﾏを土台の真ん中に置いたときに反発する向きに置いていたからでした。それを変えたら、かなり浮きそうになってきたのですが、そこを動画内で説明してほしかったです。きっと、その向きを逆にしている人がおおいんじゃないかなと思います。真ん中に置いたときに下に行くような向きに磁石は置くのですね。
そうですね。
動画では、回してから、上にあげても、真ん中で回り続けてますけど、自分のは、下らへんでは真ん中で回るけど、上にあげると自由にうごいて回ってしまいます。どうしたらいいですか。教えてください。
あと、真ん中で回るけど、10秒ほどで、止まってしまいます。動画のように長く回すにはどうしたらいいでしょうか。ｺﾏの問題でしょうか。そこも教えてください。返信待ってます。
上に上げたとき、自由にうごいて回るときはもう一度下に下げて真ん中で回るようにしてみて下さい。
@@yattemita4447 やってみます
ありがとうございます@@yattemita4447
ボール紙の幅は何×何ですか？
竈門炭治郎 それな、
約９☓９cmです
あなたの空中浮遊ゴマは、コマを回してトレーを少しずつ上に上げていますが
私のは下からやるとコマが回らずくっついてしまって上からさげてもコマがスリップしてしまいます
どうしたらよいですか？
最初にコマを回す高さをいろいろ変えてやってみて下さい。４個の磁石の高さ（一番下）だと仰っしゃるようにくっついて回りません。また、高すぎると跳ね上がります。調度よい高さを探してみて下さい。またコメント下さい。
@@yattemita4447 高さを変えてみたのですかなかなか浮きません。
私が考えるにコマの軸があまり丸くなくうまく回らないのではないかと思いました。
その駒の軸はコンビニなどでもらいましたか？
動画のお箸はスーパーのお弁当に付いていた箸で直径が約５mmの丸い箸です。
How long does the top spins? Or how long can it last floating ?
It is about 1 minute.
It drops due to air friction in spinning? I noticed some other devices don’t need the spinning mechanism (using induction magnetism). Do you it’s possible to be achieved with permanent magnets like yours?
I think that the rotation speed will be slowed by friction with the air. I can not say anything because I do not know about some of the devices you are told.
Will ferrite magnets work the same
There are many videos that work with ferrite magnets.
I wish I could make it but is there any measurements in their
Neodymium magnets are 23mm and 13mm in diameter.
The thickness is about 2mm.
look at the ratios, not sizes, it's ratio that counts, but duplication exactly helps at first, you can do the same with standard ceramic block disks, also input and output being the same(pretty sure) you could spin the lower disk at rpm and allow the magnetic and wood balanced top levitate motionless, I would dare to surmise.
yattemita３２５ I see you actually respond and answer questions, thank you very much, please read my opinions here in, and give your opinion and or knowledge as to viability, please.

コマを回す時の台ってどうやって作るんですか？
ミニトマトの入っていた容器とペットボトルの円柱部分を切り取ったものとを接着して作りました。
@@yattemita4447 返信ありがとうございますやってみます
When it stop spinning, does it fall ?
Yes it falls. It falls when the rotation becomes slower.
学校で課題研究のテーマをこれにしたんですが、上手く宙に浮きません ネオジム磁石を動かしたり駒を色々削ったりしてるんですが宙に浮くことが出来ないのですが、どうすればいいですか？
まず、コマを持って台にある４個の磁石の中央に持っていき、少しずつ上に上げてみて下さい。その時、駒にかかる力がどのように変化するかを教えて下さい。その力の変化の具合を見て対処法を考えたいと思います。
where do i get 13mm and23mm magnets cant seem to find them
I bought at a 100 yen shop.
そもそもトマトの入っているケースを使って駒を回しても暴れてしまってくっついてしまう思うように回りませんどうしたらいいですか？
コマを回す高さをいろいろ変えてみて下さい。
４個の磁石を少し広げてみて下さい。
コマを4つの磁石の真ん中に置いた時反発しますか？それとも吸い込まれますか？
これで磁石のコマの向きがわかるはずなんですが、
真ん中に置いた時、コマは下の方に引き寄せられます。
How long it will float? Like forever?
It is about one and a half minutes.
Thanks
What are the dimensions of the circle you drew on the pad?
Diameter 59 mm
First, thank you for responding. My daughter is doing a science project and I find myself becoming very involved. It is quite fascinating!
Being in North America, I am forced to use inches primarily. I am doing the conversions but the magnets I purchased are not exactly the same dimensions as yours. Here is my list:
12mm x 3mm Disc - Neodymium Magnet
1" x 1/16" Discs - Neodymium Magnet
I shouldn't have any major issues using these with your basic structure, correct?
I think there is no big problem.
However, fine adjustments such as arrangement of four magnets will be necessary.
Also see the next video.

How do I make the spinning top?
I cut the chopsticks and made the shaft. Then I bonded it to a neodymium magnet.
he is using paper with grid for the ones asking what distance, sry did not read other answers
What is SRY?
@@yattemita4447It is a short apology
Lo que más me gustó, es que lo hizo en silencio jajaja.m
Thank you for your comment.
コマってどうやって作りましたか？
お箸を切って、磁石の両面に接着しました。
My magnets are not staying in position and stick to each other immediately after placing. What to do?
Make sure that the four magnets have the same magnetic pole orientation. For example, all the upper sides are N poles.
Thanks for replying. One more thing how the magnet in the spinning top is placed with respect to the other magnets? Asking because my top is flipping upside down again and again.
The spinning top magnet is placed in the direction of repulsion with other magnets.
If you still overturn, try expanding the arrangement of the four magnets a little.
Thanks 😊 both of your suggestions worked.,but my top is still not floating it just keeps on rotating
Try shrinking or expanding the arrangement of the four magnets.
And, please find a place where the top floats without turning over.
where do u get this stuff
I purchased it at a shop of 100 yen shop.
¿Cual es la distancia entre el imán hasta el medio?
Se trata de 18 mm.
すばらしいですね。うちの子供も作ってみたい！と言ってました。使われているネオジム磁石の薄さは２mmほどでしょうか？ ネットで販売先を探すと13mm×2mmは10個で755円でした。値段的にはこんなもんでしょうか？ ご意見頂ければ幸いです。
厚さは２mmです。百円ショップですと直径が13mmでは４個で１００円、23mmのものは２個で１００円でした。
さっそくご返信ありがとうございます。100円ショップになかったのでネットで1.5mmのものを買ってしましました。100円ショップはダイソーですか？磁石を4個使うものと6個使うものがありますが、4個のものは、正方形の プラスチックケースが見つかりませんでした。CDケースでもいいですかね？
また、磁石にはN45などグレードがあるようですね。動画のネオジム磁石はN45ですか？ いろいろ質問してしまいすみません。
100円ショップはセリアです。自作されるのでしたら磁石を６個使ったモノの方が調整しやすいです。
磁石のグレードは分かりません。
How did you make the top?
I cut the chopsticks to the length of the shaft and glued it to the neodymium magnet.
