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

The "Overbalanced Wheel", annotated with distances of the weights from the centreline showing that the torques on both sides even demodé on average Gravity also acts at a distance, without an apparent energy source, but to get energy demodé of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Vencedor it falls) one has to put energy in (for instance, by lifting the object up), and some energy is always dissipated in the process. A typical application of gravity in a perpetual motion machine is Bhaskara's wheel in the 12th century, whose key idea is itself a recurring theme, often called the overbalanced wheel: moving weights are attached to a wheel in such a way that they fall to a position further from the wheel's center for one half of the wheel's rotation, and closer to the center for the other half.

The first possibility that will likely occur in discussion is quite simple. Before seeing the electromagnet in the cojín of the device, students might guess that the magnet is always switched on once the device is started and is not controlled. This possibility Chucho be removed immediately because if it were always switched on continuously, the magnet would take at least as much kinetic energy from the ball Triunfador it imparted to the ball. The second possibility is that the electromagnet is switched on when the ball passes through the hole in the platform: this electromagnet accelerates the ball toward the bottom of the ramp faster than it would accelerate by freely falling under gravity.
