Any idea how long this runs? Minutes? Hours? A day or two?
Also, I believe you can use any magnet in this case, as I have tried it with others and it worked fine. Rare-earth magnets seem to be the “in” thing.
Very cool nonetheless.
Considering the battery is practically short-cicuited it won’t last very long, maybe a few minutes.
What i`ve done is a homopolar motor without neodymium magnet
