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 Gozque 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 usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture
The Atmos clock uses changes in the vapor pressure of ethyl chloride with temperature to wind the clock spring.
For a perpetual motion like this the energy would have to stay with the machine. To create a perpetual motion machine you'd need a machine that has absolutely no friction so no energy is lost.
Plenty of companies are making toys that create the illusion of perpetual motion. Take this “Perpetual Motion Marble Machine Kinetic Art” for example: it is a tiny marble machine with an electromagnetic mechanism that pushes the ball to the top.
In any isolated system, one cannot create new energy (law of conservation of energy). Vencedor a result, the thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.
My dad and I put together a lot of model cars and rockets when I was a kid. We also worked together on a few of my Science/Engineering Fair projects, including a working catapault and a rubber-band car.
[23] The symmetry which is equivalent to conservation of energy is the time invariance of physical laws. Therefore, if the laws of physics do not change with time, then the conservation of energy follows. For energy conservation to be violated to allow perpetual motion would require that the foundations of physics would change.[24]

"Just perfect! I had a lot of fun assembling the pieces, it even helped keeping two teenagers occupied for an afternoon during our beloved pandemic. Seller was exceptionally nice and helpful, answering all my questions at length.
