World's Simplest Electric Train 【Ver.2】

This is the world's simplest electric train which runs not only inside but also “outside” the coil.

This “Train” is made of neodymium magnets, copper wire and a dry cell battery.
Please enjoy watching this simple structure electric train (electromagnetic train).

【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 dry battery, neodymium magnets (something 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.

Let's try to make it with children!

【動く仕組み・作り方】

今回はコイルの内側だけでなく外側も走れるようにしました。
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。
お暇なときにお子さんたちと一緒に作って遊んでみてはいかがでしょうか。

Thank you for watching my video. See you again!

[thecrowbarfoogle]

On tube= Normal train
In tube= Bullet train

[towatchvideos]

I want to see an actual train in human scale work like this.

[superiorredditor]

Gonna have to wait another 4 years for this recommendation... ..

[r.szajsung]

Very smart! Congratulations! It inspired me to try this myself, and teach my kids about electromagnetism by playing.
Thank you!

1:34 just a minute, let me grab a pen

[michellec.]

Did today with my son in 2023! Great and simple, last minute science project. The comments below the video were helpful to write how this works on his cardboard presentation. Thank you!

[awadheshyadav]

Why I did I not find this before my school's science exhibition 😂😂

[ChristianCabia]

Nobody expected that piece of paper on the last part xD

[Freeplay]

❤i have thes idea in my mine thes last 4 years, i dont know if it could happened or not❤but you did it ❤👏👏👏❤

[HLDUPWAlTAMINUTE]

I don't know why but this is just really mesmerizing to watch

[viditparab]

enough of those thomas toys !!
i want this one

[Potatinized]

next station: this exact station.

looks really fun tho.. I wonder how my little girl would react if I do this for her.

[stonesphixsballer]

THANK I now have an idea for a science project. : D

[hajjabdo]

بصراحة ابعداع فن تصمم ونموج وتجربه شي متقدم أحب فن اسلوبك ونموج وتجربه الرائعة والمفيده حلووووو 😍 استمرار هو نجاح

[kryptomaniac]

This is the coolest thing i have watched in my life... My life is complete.... Now i can die peacefully..

[mikespalding]

Amazing! Thank you for uploading this. This will be a great scout project for the electricity merit badge.

[Redeemer]

there is a lot of energy lost to friction with this design, however as the magnets are not superconductive. The battery will probably lose charge pretty fast. Amazing stuff though. Cool how the magnets act as both the circuit connection and the magnetic pushing force. Elegant.

[YeenVibes]

I didn't know this is what I needed at 3am, but I'm glad to have found it.

[geezer]

An excellent way to demonstrate and probably inspire kids to learn some science.

Brilliant.
