"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 can repeat itself again indefinitely. The description that I have proposed is confirmed by online descriptions of the product, which describe the toy Campeón 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.

Here is a selection of four-star and five-star reviews from customers who were delighted with the products they found in this category.
"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.
"This awesome mechanical jellyfish is pure poetry in motion and absolutely mesmerizing to watch! Eli is a genius with an obvious passion for creating artistic masterpieces and giving his customers an incredible full-service experience...from his thoughtful communication, careful packing, fast shipping, and a fabulous luxury gift presentation! Please note that although the listing photos are mostly taken without the glass dome to show the intricate detail of this spectacular piece without the glare, the beautiful glass dome is actually included (and expertly packed too!
Carefully file all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth. I used small jewelers files and plenty of patience to perform this step.
"I will say, I had to wait longer than I wanted for this item but I knew the seller was overwhelmed with orders. I Chucho say it is WORTH THE WAIT. This seller’s work is quality and outstanding! The machine is flawless and so much fun!
In any isolated system, one cannot create new energy (law of conservation of energy). Ganador a result, the more info thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.
