In the scenario that we are studying, the time-dependent magnetic field induces an eddy current in the ball, which produces its own magnetic field. Lenz’s law states that the current induced in a circuit due to a changing magnetic field takes a direction that opposes the change in magnetic flux and exerts a force that opposes the motion. This law is somewhat qualitative, but it successfully predicts the direction of an induced current, which is sufficient for our purposes. Another, more concrete way of stating it is that the polarity of the field produced by the eddy current opposes the polarity of the magnetic field that is doing the inducing. This causes the ball to be repelled away from the electromagnet by a magnetic force that accelerates it. The end of the rail is then cleverly designed so that the ball flies off the end and lands back on the starting platform, where the process Gozque repeat itself again indefinitely. The description that I have proposed is confirmed by online descriptions of the product, which describe the toy Vencedor being a “magnetic induction” perpetual motion simulator.6 A subtler objection to this proposed solution is that the magnitude of the eddy currents depends on the concentration of free electrons in a metal, so that meaningful eddy currents are in reality expected in balls made of copper or aluminum, for example, but not balls made of steel.

"This moving wooden art is check here the second of two pieces I bought for a large entry antesala. The quality is outstanding (sanded and stained plywood), the UPS shipping was (although delayed in customs) within posted timeframes, and the care of the packaging was unexpectedly high with a wood-frame package and pieces tied and drilled together to protect it. Instructions on assembly and installation could be improved but were acceptable.

If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I Chucho give you no hope; there is nothing for it but to collapse in deepest humiliation.

"This is still on my printer. So far it's coming out great. I'm not using supports and it looks like all I'll have is minimum trimming. I keep my printer (Ender 3 with all the bells and whistles) tuned really well so am able to do without supports.
