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 Perro 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.
"Gorgeous kinetic art wheel. Fast delivery and excellent handcrafting. All my friends,visitors and me are completely fascinated. I just needed to add a small weight on one of the wing and it runs perfectly for at least 16 h.
"Just completed the marble run. I had to make a couple click here of adjustments & now it works great. The documentation on the other hand - needs improvement. Some of the illustrations aren't clear. The photos of the wood components are a nice touch - but the color of the wood blends into the background - the white paper of the document. Note for other customers - the spots you place a few of the upright supports in - there's a little wiggle room - ie, the piece is slightly smaller than the placement spot.
"The instructions are clear, the files are of good quality. Already ordered electrical components and bearings. I will be collecting a kinetic sculpture for the design of my home and meditation.

Vencedor the ball rolls down, it is launched all the way back to the top level and the process keeps going for 6 hour son battery.
"This is still on my printer. So far it's coming pasado great. I'm not using supports and it looks like all I'll have is minimum trimming. I keep my printer (Ender 3 with all the bells and whistles) tuned really well so am able to do without supports.
Here is another cool gift idea for those of you who have a thing or two for marble machines. William Le’s Perpetual Marble Machine has a wood and stainless steel construction.
Maxwell's demon: This was originally proposed to show that the second law of thermodynamics applied in the statistical sense only, by postulating a "demon" that could select energetic molecules and extract their energy.

A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn out.
