something breaking the first law of thermodynamics

Then there are versions with magnets,like this set of ramps.The ball is supposed to be pulled upwards by the magnet at the top,fall back down through the hole,and repeat the cycle.This one fails because like the self-watering pot,the magnet would simply hold the ball at the top.Even if it somehow did keep moving,the magnet's strength would degrade over time and eventually stop working.For each of these machines to keep moving,they'd have to create some extra energy to nudge the system past its stopping point,breaking the first law of thermodynamics.
