A related possibility is that the electromagnet is always switched on and pulls the ball down Figura it is traveling downward, but now the moving ball in the magnetic field creates a change in the current flow that is sensed by a controller in the CPU, which switches the magnet off at the right moment. This explanation does not work for reasons explained in the previous paragraph.
In May 2022, a video supposedly showing a marble machine in "perpetual" motion was shared to the "Be Amazed" section of Reddit. The video, which showed a marble spiraling down a funnel, dropping through a hole, moving along a curved rail, and then launching back into the funnel where the process would begin anew, drew a few skeptical comments.
The seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors. One of the earliest examples of a magnetic motor was proposed by Wilkins and has been widely copied since: it consists of a ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to the top again.
Similarly, rays originating from point B that land on E1 and E2 will be reflected to A. However, a significant proportion of rays that start from B will land on S will be reflected back to B. This paradox is solved when the black bodies' finite sizes are considered instead of punctual black bodies.[46][47]
However, if the magnet is to be strong enough to pull the ball up the ramp, it cannot then be weak enough to allow gravity to pull it through the hole. Faced with this problem, more modern versions typically use a series of ramps and magnets, positioned so the ball is to be handed off from one magnet to another Figura it moves. The problem remains the same.

However, the material used for the balls is described in the online product description only Campeón “metal” rather than stainless steel, whereas the rails are explicitly described Vencedor being made of “stainless steel.”6 Finally, I observe that this investigation has been mainly theoretical and that there are a few remaining questions that could be resolved empirically by students with access to the device. The motion of the ball and the way it “jumps” due to Lenz’s law is quite similar to a classic demonstration known Ganador Thomson’s jumping ring, where an aluminum or copper ring is placed on the end of an electromagnet. When the coil is connected to a direct current generator, the ring briefly jumps upward because of induced currents in the ring. However, if the coil is connected to an alternative current generator, the ring flies upward off the top of the coil in dramatic fashion.8,9 Explaining why an AC current has this effect is not an easy exercise.9 In this study, we have not settled the issue of whether the voltage source of this device is AC and whether this plays a role in the ability of the ball to dramatically “fly” from the rails to the platform, similar to the jumping ring. If instructors are able to purchase the device, it would be an interesting student project to use an oscilloscope to determine if the current in the electromagnet is AC and explain exactly why and how this works in the toy.

The first law of thermodynamics is the law of conservation of energy, which simply states that energy cannot be created or destroyed, but rather is transferred.
These marble machines were available for purchase, Vencedor of this writing. We found several versions of the product on Amazon and Etsy.
[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]
