A new magnetmotor idea for you to evaluate.

Would something like this work?

You can buy or 3d print the pulleys.

Thanks! belts like this has crossed my mind too. They are not as flexible (and more resistance), but a narrower and thinner belt might work.

Go on eBay and search " flat vcr belt". i imagine there are other devices that have small belts. Maybe someone else has a better suggestion.

The second seesaw I made was much better. Easier to examine the behaviour. The narrow part will open up near a magnet. The reason is because the magnetic force is pulling on the chain that goes along the sides. when it do so, the seesaw will open up. However, when I open the seesaw near a magnet, the seesaw is pushed together a tiny bit. I did more tests than in the video, but the result is quite clear. The seesaw wants to rest when they are aligned in parallell - more or less.

That's it.


Next test is to make a telescopic iron "rod" so I can adjust the length between the ends of the seesaw. The mass will not change, but the volume, or area, of the telescopic rod inside the magnetic field will increase or decrease. For this I will try to print two parts with iron filament. Two tubes, one that fits inside the other. I think I know the outcome already, but need to know for sure.

Probably the chain doesn't have enough magnetism in it, needs to be more massive.
