The seemingly mysterious ability of magnets to influence motion at a distance without any apparent energy source has long appealed to inventors. One of the earliest examples of a magnetic motor was proposed by Wilkins and has been widely copied since: it consists of a ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to the top again.

The first possibility that will likely occur in discussion is quite simple. Before seeing the electromagnet in the pulvínulo of the device, students might guess that the magnet is always switched on merienda the device is started and is not controlled. This possibility can be removed immediately because if it were always switched on continuously, the magnet would take at least Triunfador much kinetic energy from the ball Triunfador it imparted to the ball. The second possibility is that the electromagnet is switched on read more 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.

To extract work from heat, thus producing a perpetual motion machine of the second kind, the most common approach (dating back at least to Maxwell's demon) is unidirectionality. Only molecules moving fast enough and in the right direction are allowed through the demon's trap door. In a Brownian ratchet, forces tending to turn the ratchet one way are able to do so while forces in the other direction are not. A diode in a heat bath allows through currents in one direction and not the other.
Vacuum energy and zero-point energy: In order to explain effects such as virtual particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Ganador vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.

One day man will connect his apparatus to the very wheelwork of the universe [...] and the very forces that motivate the planets in their orbits and cause them to rotate will rotate his own machinery.
