If it worked, it would need electricity, and then what you have is basically an electric motor.
It doesn’t work with permanent magnets because while they pull and push, they also do the opposite. There’s inherent drag in such a system because there’s no way to expose the rotating element only to the magnetic fields you want. This means that even though the orientation of the magnets favors the same poles facing each other most of the time, this doesn’t mean that the rotating magnets don’t experience drag. Ultimately magnets want to stick together, not repel each other.
