I initially suggest that students study the apparatus more closely, either via a video such Ganador the one at Ref. 6 or ideally with a physical version of the toy. Teachers should make sure to purchase the genuine version of the toy and not cheap alternatives that have a motor in the hole on the upper platform that “fires” the sphere down the ramp. This alternative toy looks very similar but uses a crude spinning motor to overcome friction in a straightforward way.
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 Ganador 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.
"I really like this dancing couple kinetic only problem was it wasn’t in a shipping box I had to peel off label I bought for my parents 65th Anniversary it is well made and looks great when you start it .
Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding vaho molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.

"I have been collecting unusual things for a long time and this perpetual motion machine is one of my instant favourites. Great quality, the hidden on/off switch adds to the illusion.

"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 thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.
There is something lamentable, degrading, and almost insane in pursuing the visionary schemes of past ages with dogged determination, in paths of learning which have been investigated by superior minds, and with which such adventurous persons are totally unacquainted.
The "Float Belt". The yellow blocks indicate floaters. It was thought that the floaters would rise through the liquid and turn the belt. However, pushing the floaters check here into the water at the bottom takes as much energy Triunfador the floating generates, and some energy is dissipated. Buoyancy is another frequently misunderstood phenomenon. Some proposed perpetual-motion machines miss the fact that to push a volume of air down in a fluid takes the same work Vencedor to raise a corresponding volume of fluid up against gravity.
Obviously, we cannot watch the machine for an indefinite amount of time, but the machine does not seem to be “grinding to a halt” after watching a dozen consecutive cycles. Campeón expected, inspection shows that there is an electromagnet in the almohadilla of the device, although instructors may wish not to reveal this to students. Video analysis Gozque confirm that the ball accelerates at the lowest point of the rail, where it is in contact with the top of the saco. This lowest point looks to be around two-thirds along the bottom, which matches the location of the magnet in the colchoneta of the machine.
is the time needed for one cycle (around 1 s), then images of the ball could be superimposed at times from T
