That train is fast considering how simple it is!
The simplest electromagnetic train ever vs a toy pull back car. The train is really easy to make but the speed it gets to is nuts. If it was longer it looks like it would just keep speeding up. It’s only a battery a few magnets and coiled up copper. That’s all it takes for this and you can build one. It’s also interesting to see how the magnets size and power can affect the speed so much and how he was able to speed it up with a few minor adjustments.
