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

Our first inclination when we saw this video was that its creators used digital animation. We've encountered several similar seemingly "impossible" videos featuring colored ball sorters and musical marbles that used computer-generated technology. The latest video supposedly depicting the "perpetual" marble machine, however, was authentic footage and featured a physical product.

With the exception of cases involving perpetual motion, a model is not ordinarily required by the Office to demonstrate the operability of a device.

A capillary action-based water pump functions using small ambient temperature gradients and vapour pressure differences. With the "capillary bowl", it was thought that the capillary action would keep the water flowing in the tube, but since the cohesion force that draws the liquid up the tube in the first place holds the droplet from releasing into the bowl, the flow is not perpetual.

Since weights further from the center apply a greater torque, it was thought that the wheel would rotate forever. However, since the side with weights further from the center has fewer weights than the other side, at that moment, the torque is balanced and perpetual movement is not achieved.[28] The moving weights may be hammers on pivoted arms, or rolling balls, or mercury in tubes; the principle is the same.

The first law of thermodynamics is the law of conservation of energy, which simply states that energy cannot be created or destroyed, but rather is transferred.

So, for example, the thought experiment of a Brownian ratchet Figura a perpetual motion machine was first discussed by Gabriel Lippmann in 1900 but it was not until 1912 that Marian Smoluchowski gave an adequate explanation for why it cannot work.[26] However, during that twelve-year period scientists did not believe that the machine was possible. They were merely unaware of the exact mechanism by which it would inevitably fail.

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).

Hollis Williams is a postdoctoral researcher at King Abdullah University of Science and Technology. He is interested in various aspects of physics education and theoretical physics and has published articles on fluid dynamics, quantum mechanics, and particle physics.

/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.
