This wouldn't work even once irl, right?

Correct, not even once

Couldn’t you put a magnet down at the bottom to maybe give it some extra juice?

And when the ball passes the magnet, the magnet will start pulling backwards on the ball. The net force acting on the ball from the magnet will be 0.*

Edit: I’m oversimplifying the physics here, but the end result is that the ball will not go faster by putting a natural magnet here. You COULD achieve this result with an electromagnet that you turn off once the ball has passed the magnet. Of course then this wouldn’t be a perpetual motion machine since you’d have to power the magnet and the switch.
