The correct explanation involves electromagnetic induction. The electromagnet is always switched off and is then switched on
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.

A perpetual motion machine of the third kind is defined Ganador one that completely eliminates friction and other dissipative forces, to maintain motion forever due to its mass inertia (third in this case refers solely to the position in the above classification scheme, not the third law of thermodynamics).
The get more info history of perpetual motion machines dates back to the Middle Ages.[13] For millennia, it was not clear whether perpetual motion devices were possible or not, until the development of modern theories of thermodynamics showed that they were impossible.
A more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no net gain. Thus, the device would not violate the laws of thermodynamics.
