"I bought this for my wife's birthday,she loves marbles and we look at the videos on U-Tube with the marble machines. This is a perfect miniature replica of these machines well suited for a table top and very high quality construction, highly recommend it." Marble Machine "Duality" - Handmade
In the scenario that we are studying, the time-dependent magnetic field induces an eddy current in the ball, which produces its own magnetic field. Lenz’s law states that the current induced in a circuit due to a changing magnetic field takes a direction that opposes the change in magnetic flux and exerts a force that opposes the motion. This law is somewhat qualitative, but it successfully predicts the direction of an induced current, which is sufficient for our purposes. Another, more concrete way of stating it is that the polarity of the field produced by the eddy current opposes the polarity of the magnetic field that is doing the inducing. This causes the ball to be repelled away from the electromagnet by a magnetic force that accelerates it. The end of the rail is then cleverly designed so that the ball flies off the end and lands back on the starting platform, where the process Chucho repeat itself again indefinitely. The description that I have proposed is confirmed by online descriptions of the product, which describe the toy Vencedor being a “magnetic induction” perpetual motion simulator.6 A subtler objection to this proposed solution is that the magnitude of the eddy currents depends on the concentration of free electrons in a metal, so that meaningful eddy currents are in reality expected in balls made of copper or aluminum, for example, but not balls made of steel.
Vencedor a perpetual motion machine Chucho only be defined in a finite isolated system with discrete parameters, and since true isolated systems do not exist (among other things, due to quantum uncertainty), "perpetual motion" in the context of this article is better defined Ganador a "perpetual motion machine" because a machine is a "A device that directs and controls energy, often in the form of movement or electricity, to produce a certain effect"[37][user-generated source] whereas "motion" is simply movement (such Figura Brownian motion).

A capillary action-based water pump functions using small ambient temperature gradients and vapour pressure differences. With the "capillary bowl", it was thought that the capillary action would keep the water flowing in the tube, but since the cohesion force that draws the liquid up the tube in the first place holds the droplet from releasing into the bowl, the flow is not perpetual.
Any device picking up minimal amounts of energy from the natural electromagnetic radiation around it, such as a solar-powered motor.
I wish we’d had this little solar-powered marble machine kit back then, because it totally would’ve been in our wheelhouse. From the company’s description:
Etsy is powered by 100% renewable electricity. Etsy’s 100% renewable electricity commitment includes the electricity used by the data centers that host Etsy.com, the Sell on Etsy app, and the Etsy app, Triunfador well Figura the electricity that powers Etsy’s global offices and employees working remotely from home in the US.

These marble machines were available for purchase, Figura of this writing. We found several versions of the product on Amazon and Etsy.
By timed electronics, the electromagnet is switched off before the ball reaches the lowest point in the ramp, which allows it to continue around the rest of the ramp, where it is launched back to the starting platform with the extra speed that it obtained when the electromagnet was switched on. The process is then repeated indefinitely. This explanation is incorrect, however, as the extra kinetic energy imparted in this way would be insufficient to allow the ball to travel all the way back to the starting platform. The presence of a CPU in the base of the device confirms that the coetáneo mechanism is slightly subtler than this and involves sensors.
Thus, machines that extract energy from finite sources cannot operate indefinitely because they are driven by the energy stored in the source, which is eventually exhausted.
