I initially suggest that students study the apparatus more closely, either via a video such Campeón 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.

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 toy that I have mentioned seems to be a relatively plausible example of perpetual motion. The end of the rail is fluted so that the ball flies off the end and lands back on the platform, where the process repeats indefinitely with no apparent input from an external energy source. Figure 1 shows a view of the device from the side. One can see that the ball slides down a pair of rods that are placed side by side.
For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts Campeón opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.
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.

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.
