How to make World's Simplest Electric Train 【世界一簡単な構造の電車】

【Structure and How to make】 ※日本語での説明は欄の下

It's possible to get such power using a 1.5V alkaline battery, neodymium magnets (super strong magnets with plated with metal) and a bare copper wire.
A point is that a magnet's diameter is bigger than a dry cell battery's diameter.
And an electric current flows to a coil through a neodymium magnets, and a coil will be an electromagnet only in an area between the magnet and the magnet.
The electromagnet and a neodymium magnet poles repel each other at one side.
The other side poles pull against each other.
They work same direction, and it become a big force.
The phenomenon also continues at a movement destination.

※Another important point is magnets direction
(e.g.) NS battery SN

Thank you for reading.

How about making this electromagnetic train for science fair projects?

【動く仕組み・作り方】

1.5Vのアルカリ乾電池、ネオジム磁石（メッキされているもの）、裸銅線を用いてこのような動力を得ることが出来ます。
ポイントは、磁石は乾電池の直径より大きいものを用いることです。
それによりコイルにはネオジム磁石を通して電流が流れ、磁石と磁石の間の区間だけはコイルが電磁石になります。
その電磁石と中のネオジム磁石が片側では反発し合い、片側では引き合い大きな推進力となります（同じ方向に力が働く）。
そして、それが移動先でも続きます
ただし、そのような動力を得るためには、磁極の向きが重要で、両端が同じ極、例えば、

NS 乾電池 SN

という具合にする必要があります。
お子さんたちと一緒に作って楽しみながら科学に触れみるのはいかがでしょうか。（自由研究などにも良いかもしれませんね）

i really appreciate the efforts to make the tutorial as language free as possible, literally anyone can understand. great video.

Thank you for watching my video.
See you again!

[KeritechElectronics]

You explained it with (almost) no words and did it so clear that Ikea can take lessons from you right away :)

[zhiwen]

I really appreciate how you tried to
make this video understandable to all languages.

[jackbisson]

That is a great way to teach with out having to speak. Well done!

[tigresuave]

Thank you so much, I can't wait to make this with my son!

[FrodeForhammer]

this is brilliant! im gonna do this myself :D

[AdityaJha]

Thats why japanese technology is Love from India 🇮🇳❤️

[philmcrakin]

Quite possibly the best tutorial I've seen to date.. Not sure it could have been explained any better.. Nice one, thanks..

[ingeniero]

por fin veo un vídeo bien explicado gracias amigo me encanto =)

[crisbenfabella]

I want this for my nephew he enjoy this for sure, unlimited spinning

[egonforgotten]

I love the detail, and I love the style! But most of all, I love the science! But I still have no idea what kind of batteries and magnets here's using 🙁

[carrotlab]

You cannot understand how shocked I am when I was watching this video. To show an experiment can always be tedious, messy and you have to listen to 1000 terms. But this video is so simple, clear and elegant. And they achieve all this in silence. This really explains how great the Japanese mind can be. It is even not about how brilliant your idea is, but how you explain! Thank you so much.

Wait hold on. theres a battery... oof

[offon]

Прекрасный урок физики для школьников 👍👍👍👍👍

[prairiemountaineer]

wow. not a single word, yet crystal clear tutorial. Keep up the great videos!!

[JohnTurger]

Then in this way I can make myself a personal subway to work! :D

[abpccpba]

Wonderful video. Will try it again; used wrong wire. Determining magnet poles was pure genius; monster compass in hiding. Thanks.

thank u for explaining it in the, easy way
