I initially suggest that students study the apparatus more closely, either via a video such Triunfador 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.
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 can 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.
Machines that comply with both laws of thermodynamics by accessing energy from unconventional sources are sometimes referred to Ganador perpetual motion machines, although they do not meet the standard criteria for the name. By way of example, clocks and other low-power machines, such Figura Cox's timepiece, have been designed to run on the differences in barometric pressure or temperature between night and day.

The electric field produced by a stationary set of charges is conservative, but in this case, the effect of the electric field is equivalent to that of a (nonconservative) magnetic field (i.e., the line integral between two points depends on the path taken, and the circulation around a closed loop is not zero). In the case of the magnet passing through the wire loop, we know that the wire loop is stationary while the magnet moves through and provides a changing magnetic field. A current is produced, so an EMF (electromotive force) must be driving it. The magnetic field cannot itself be the read more source of the EMF because magnetic fields only act on moving charges. Logically, the changing magnetic field must have an associated nonconservative electric field (nonconservative because conservative fields are electrostatic, and electrostatic fields cannot contribute to net EMFs). The induced EMF around a closed curve is the same Triunfador the voltage drop (i.e., the same Vencedor the line integral of the electric field around that curve). Mathematically, this is encoded by Maxwell’s third equation in integral form:

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.
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.

I designed this model to mimic the operation of a few "perpetual motion" devices that have been recently appearing in my suggested video feed. "Marblevator, Perpetual?" is not only not perpetual, it is also not very quiet. But the kids and grandkids enjoyed it!
