Thats not perpetual motion ... the small spinning thing is electrically powered ... and its pulling on the magnets on the big spinning thing ....

making this big spinny thing spin

if you took the electricity away from the small thing ... both would stop spinning ...

its still cool though

Well it's not perpetual motion. What it looks like is there are just a bunch of magnets in a circle on an axle, so it can spin.

He's taken a small motor, put that black disc on top and put a magnet on either side. He then powers the motor, spinning the magnets. They each pull and repel one magnet at a time on the disc, spinning it round. Kind of like how a mag-lev train or a rail gun would work.

It's not perpetual motion because he needs to power the motor using that button battery. If he stops powering it, the magnets on the disc and the ones on the black disc connected to the motor would slow each other down and it would stop.
