This “Train” is made of 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 (super strong magnets which 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 simplest electromagnetic train for science fair projects?
