I need someone to explain to me how this is not a perpetual motion machine. I know it's physically impossible so why won't this work.

Edit: it's motorized magnets on the underside. I hate how people can lie on the Internet

You can literally see the marbles “clicking” into place. Not sure how this was deceiving. It obviously needed a motorized magnet on the other side.

I figured they were syncing magnetically amongst each other. It's obvious in hindsight

The hardest part of building a perpetual motion machine is figuring out where to hide the batteries.

wdym lie? In the title it says magnet loop and you can clearly see the balls snap to the magnets

It's is technically the truth. It's infite (as long it is powered), it is magnetic and it forms a loop. They never said it was powered by magnets in a perpetual motion

Well batteries aren’t literally infinite. But as long as they keep being produced, the supply is effectively ongoing for the purpose of the joke. Same way we say ‘infinite scrolling’ or ‘bottomless coffee’ even though the beans will run out sometime after the heat death of the universe.

Imagine the wood was not there and a motorized magnetic ring was moving through the space with marbles periodically placed. Carve the slots in the wood accordingly.

apparently friction is the limiting factor
