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.

The seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors. One of the earliest examples of a magnetic motor was proposed by Wilkins and has been widely copied since: it consists of a ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to the top again.

"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture
As 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.
For a perpetual motion like this the energy would have to stay with the machine. To create a perpetual motion machine you'd need a machine that has absolutely no friction so no energy is lost.

The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral.

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 into the water at the bottom takes as much energy Figura 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 as to raise a corresponding volume of fluid up against gravity.
Link Drop a marble into the top of this tabletop sculpture, and it rolls down a ramp and back into itself endlessly.
A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn demodé.
