"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 .
Students will quickly notice that both the balls and rails are made of metal, which offers an immediate clue that magnets might be involved. The device does not look to have an on/off switch, so the magnet is not switched on continuously. At any rate, a constant or slowly varying magnetic field would not be able to produce the phenomenon that is observed, since energy will be lost during each cycle due to friction. Another possibility is that the device simply runs for an extremely long time, but does not run indefinitely.
"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.
"I recently had the pleasure of purchasing a stunning kinetic wall art piece from the talented artist, William. The kinetic wall art itself is a true masterpiece. The interplay of movement and form creates a mesmerizing visual experience, transforming my living space into an enchanting gallery. William provided exceptional customer service. From the moment I inquired about the piece to its safe and timely delivery, he displayed a level of professionalism and attentiveness that exceeded my expectations.
"This awesome mechanical jellyfish is pure poetry in motion and absolutely mesmerizing to watch!

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!
Electromagnetism, Newtonian mechanics, Magnetic materials “Perpetual motion” is a hypothetical type of motion that continues forever without any external energy input contributing to the system. Students should know that this is generally impossible because of energy losses due to friction or other nonconservative forces, or because some assumption has been made that violates the first or second law of thermodynamics (or both). The first law states that the total energy of an isolated system remains constant over time, and one of the most common formulations of the second law states that the entropy of an isolated system over time cannot decrease. Note that the laws apply to an isolated system (i.e., one that cannot exchange mass or energy with its surroundings), whereas a closed system can still exchange energy even if it cannot exchange mass.

The output work power of heat engines is always smaller than the input heating power. The rest of the heat energy supplied is wasted as heat to the ambient surroundings. The thermal efficiency therefore has a maximum, given by the Carnot efficiency, which is always less than one.

A rejection [of a patent application] on the ground of lack of utility includes the more specific grounds of inoperativeness, involving perpetual motion.
/20. This would then allow students to calculate the speed of the ball at different locations along its trajectory and quantitatively confirm the statement above that the ball obtains a burst of speed close to the bottom part of its trajectory.
