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.

However, if the magnet is to be strong enough to pull the ball up the ramp, it cannot then be weak enough to allow gravity to pull it through the hole. Faced with this problem, more modern versions typically use a series of ramps and magnets, positioned so the ball is to be handed off from one magnet to another Ganador it moves. The problem remains the same.

However, this machine has no practical purpose because the rotated object cannot do any work Campeón work requires the levitated check here object to cause motion in other objects, bringing friction into the problem. Furthermore, a perfect vacuum is an unattainable goal since both the container and the object itself would slowly vaporize, thereby degrading the vacuum.

The Atmos clock uses changes in the vapor pressure of ethyl chloride with temperature to wind the clock spring.

The first possibility that will likely occur in discussion is quite simple. Before seeing the electromagnet in the colchoneta of the device, students might guess that the magnet is always switched on once the device is started and is not controlled. This possibility Perro be removed immediately because if it were always switched on continuously, the magnet would take at least Figura much kinetic energy from the ball Campeón 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.
