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

Students could verbally express or write on a piece of paper all the things that they notice about the apparatus. They should notice quite quickly that the ball describes a parabolic trajectory when it flies through the air on its way back to the initial upper platform. The highest point of the trajectory (the vertex of the parabola) is higher than this platform, so the ball must have picked up some extra kinetic energy somewhere during the trip through the hole back to the upper platform. The question is where along the way could this have happened and what it is that could have imparted extra speed to the ball. Students should think of how they could potentially figure demodé where on the trajectory the ball is being sped up.

However, the material used for the balls is described in the online product description only Vencedor “metal” rather than stainless steel, whereas the rails are explicitly described Vencedor being made of “stainless steel.”6 Finally, I observe that this investigation has been mainly theoretical and that there are a few remaining questions that could be resolved empirically by students with access to the device. The motion of the ball and the way it “jumps” due to Lenz’s law is quite similar to a classic demonstration known as Thomson’s jumping ring, where an aluminum or copper ring is placed on the end of an electromagnet. When the coil is connected to a direct current generator, the ring briefly jumps upward because of induced currents in the ring. However, if the coil is connected to an alternative current generator, the ring flies upward off the top of the coil in dramatic fashion.8,9 Explaining why an AC current has this effect is not an easy exercise.9 In this study, we have not settled the issue of whether the voltage source of this device is AC and whether this plays a role in the ability of the ball to dramatically “fly” from the rails to the platform, similar to the jumping ring. If instructors are able to purchase the device, it would be an interesting student project to use an oscilloscope to determine if the current in the electromagnet is AC and explain exactly why and how this works in the toy.
I would highly recommend this for a gift or even for yourself Campeón a fun showpiece. It's also great to shop small and support this shop through their endeavors! So cool of I haven't said it yet, but it's so cool I highly recommend!!!" Automatic Zen Garden Sand Bowl - Kinetic Art

The shopkeeper is quick to respond to email requests for assistance. The piece read more will run for about 8 hours on a single winding (wind the bottom, motion around top), but is a little noisy for a bedroom or main room (you could always stop the motion at bedtime). Everyone loves these three pieces together, but any one of them will work as a main art piece on an appropriately large wall."
