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?

No, what he is saying, is that moving magnetic field, induces current, and can mess up the cheap power supply and/or other components, which can then mess up the drives.

In a server, the power supply is on the other end of the chasis. In a laptop, it's a lot closer to the internals.

> I don't buy that either.


The forward model:

The reverse model:

The big ones: Note: the Three Gorges: 22 GW

For comparison, nuclear power: Largest U.S. nuclear plant: Palo Verde (Arizona) produces around 4 GW.

For home applications:
