Very Fast Mechanical Mini Car vs Simplest Electromagnetic Train

This is speed challenge of simplest electromagnetic train 1.5V (compared with super clockwork mini car). Best performance is 4:40
※ In this video's Lithium battery has safety holes for gas. ※ Symbol of Φ is magnets diameter. ※Friction = advantage about friction
The standard written on the battery in this video is Alkaline (AA LR6 1.5V), Lithium (AA L91 FR6 1.5V)

This electromagnetic train is made of neodymium magnets (super strong magnets), copper wire and a dry cell battery.

【Structure and How to make】

It's possible to get such power using a dry battery, neodymium magnets (super strong magnets which plated with metal) and some bare copper wires.
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

How about making this World's simplest electric train.
