5) yes the wheel will actually keep spinning * IF you have the magnet in the right place in probably you'd need a degree in engineering to figure out correctly the way he has it demonstrated it will probably only spin for about an hour or less* 6) this argument is retarded and you ppl need to get a life if you really think you so right about a *listen now* TOY MOTOR AND A PLASTIC PHILIDEPHIA LID CREATING PERPETUAL ENERGY -_- COME ON PPL |

*facepalm* wow this big of an argument over simple phisics here we go ppl ima dumb it down real nice like so you can understand how this is actualy possible 1)yes this is actually possible ive done it before in simple in class experiments 2) as Andyl said the magnet would have to get past the the equilibrium position witch is actualy possible on a small set up like this (based on weight in the grams here ppl it dosent take alot to move it) so when one magnet moves past the hand magnet its going to be attacted fast enough that it will push threw the hand magnets strongest point in the magnetic feild were the next magnet slides into place to continue the attraction that means that its gona gather momentum and go faster and faster till it reaches a stable point were it cant continue to gain speed 4) friction -_- its a toy motor with a plastic lid theres not much friction there ( remember ppl this is stuff weighing only grams here ) |

Damn..3) Retraction. If the poles on the hand magnet are aligned tangentially to the radius of the wheel, then it *would* be attracting approaching magnets and repelling passed magnets. 3A) However, this is not a binary either/or thing. The leading edge is attracting while the trailing edge is repelling. At the exact halfway point, the leading edge is pulling the wheel back while the trailing edge is pushing the wheel back. The net effect is, the hand magnet is providing more *stopping* force than *going* force. |

4) The life of the magnets has *nothing* to do with it. This system is not going to work for a while and then stop, it will not work *at all*.5) As stated before, this system will either come to rest with one wheel magnet pointing directly at the hand magnet if it's aligned one way or with the hand magnet between two wheel magnets if it's aligned the other way. 6) The video is clearly fake. How he did it is irrelevant, but the device as shown will not work even for a little while. If you spin the wheel by hand without the other magnet it will turn and provide power for a few seconds. Adding the other magnet adds more of a load, and will stop the wheel even faster.

sigh.. This is not speculation, I do know what I am talking about here.1) Gravity is not involved *at all*. Gravity pulls down on both sides of the wheel equally and has no effect on this system. 2) Friction has *almost* nothing to do with it. The friction in this system is insignificant compared to the torque load the generator is creating. 3) The hand magnet is not attracting one wheel magnet and repelling a different one; it is either attracting *all* the magnets in its range or repelling all of them.

As we've pointed out, the magnets provide a force which can oppose the motion quite strongly. But similarly, it then provides an equal opposite force half the time when it is both repelling a magnet away AND attracting the next one in the series. So overall, the magnet should just speed up and slow the wheel if it manages to actually perform circular motion. The way I see it, the magnet effectively does nothing - it most definitely does NOT supply the system with free energy, in fact it just converts energy continuously between magnetic potential and kinetic energy. And so in the end friction will do its job and stop the wheel, as kinetic energy is lost as it's converted to heat. No fancy physics needed, it's just basic mechanics. |

Oh look now I'm fed up. Let's think about this together now. Without the magnet, what happens? Well you start it spinning, and it gradually slows down and stops due to friction. Now put in the magnet. The magnet will do one of two things. It will repel or attract a magnet on the wheel towards it. If it repels a magnet, the wheel will spin a bit until it can attract the next magnet. So now what? It's a question of whether the combined effects of gravity, friction and the magnet slow it down in time. Well as the attracted magnet moves past the equilibrium position, the combined effects of attracting the magnet back AND repulsing the next one in the series. Take away a LOT of momentum. Now considering the strength of the magnets, the likelihood of the wheel having enough angular momentum to make it past this point is unlikely. But suppose it does. What happens next? Well think about the forces in play here for a second... |

knoing little to nothing about perpetual motion but enough about teh interwebz to be paranoid- possibility that his light bulb has wires running through the table to the battery at teh start wich powers teh motor to turn teh 'magnetic' wheel?
so insted of wheel>>>>motor>>>>bulb
its battery under table>>>>bulb>>>>motor>>>wheelits just speculation but makes sense becuse it would still be a completed circuit =] |

1. There is currently a several hundred thousand dollar prize to whoever discovers prepetual motion (to my understanding)2. You think that hundreds of years of geniuses cant figure out prepetual motion, but this guy can? 3. To the comment bellow me, yes gvity does do the the effect you say, but it pulls the magnets down from the oposing dirrection aswell, for your theroy to validate his machine, you would need to some how temporarily tom gavity every (say, 10th of a second) to cancel out the opposing efect of gravity. 4. To the person that stated that magnets lose there power so this isent technically prepetual, if you want to be really technical, the 3rd law of thermodynamics means that nothing is prepetual, since and entropy will disintergrate. 5. i realise i have crappy spelling, that shouldnt make my points less valid

Jagjamin, you're close, but you're missing one or two crucial factors. For one, the wheel was at an angle and the magnet was on the lower side. Why does that matter? Once the wheel is actually spinning, the force of gravity is added to the force of the rotation. The revolution pushes it far enough for the next magnet to come within range of the pull while simultaneously pushing the first one away at the same rate (hence the even spacing).
Yes, at a stand-still, your theory is correct, but he did say in the video that it needs an initial force to get it going. It never said it takes no energy to start. Just none (Relative) to keep it going. The only problem in long terms was stated by Xithor. They lose magnetism. But, during the magnet's existing lifespan, it does have a sort of perpetual cycle to it. Does it last forever? No. Does it require energy? Initially, yes. Afterwards (if the magnets are placed properly), no. |

That is the entire art of the experiment, and the overall point of trying. To make something that needs no energy to RUN.Also, outside of this debate...Acthrellis, read the comment below yours. Irony at it's best. |

Does anyone have any thoughts on the notion of using a magnetic monopole to do this?
I mean, we don't have one yet, nor even proof that they exist, but hypothetically it might work... thoughts on that?A magnetic monopole could repel the initial, while attracting the first -- say you started the wheel spinning to give it enough momentum, couldn't it then push beyond the initial repulsion of the NN/SS and send it into the alternate side, where it would regain the lost momentum before repeating the process... Assuming all the magnets had identical strengths, anyway. But that's assuming no friction, or that light bulb, too, so maybe not :p |

This is idiotic. As soon as I read the discription I knew that this was fake. Perpetual motion machines (if they can even be made, I am not sure on that point) can never be used to do any work whatsoever. Nothing can create energy, so the only way for a perpetual motion machine to work is to never transfer any of it's initial energy out. If a machine emmits light (such as this) It is transfering energy out, and will soon run out of energy, thus no longer being perpetual. |

Is any one eelse tired of comment-section arguments everywhere you go? Or is it just me? Regardless whether they're worthwhile or not... just tired of it. At least at IAB we can spell... don't get me started on arguers with no grammar. UGH. |

I am sorry, but I cannot let such bickering continue. As a studying physicist, I have to dispel all of these false accusations. All of the people who said this is not perpetual motion are correct, total usable energy output cannot equal energy input. There is no motor turning the magnets, anyone with a nanobrain-cell can see that. Magnets would react in the manner shown. Magnets work by attracting the free electrons from one ferrous object to another. However, these magnets would not work like this perpetually. Eventually the amount of free electrons on the magnets attached to the lid would become virtually none, And the magnets would altogether stop working and have to be remagnetized. They would also not attract the closet one, as the magnetic fields around a magnet do not work in straight lines, but elliptical curves. |

Funny, I expected to see everyone shouting "fake" for one very simple reason. Watch what happens when the wheel starts spinning. Yeah, see that? It spins clockwise a very tiny amount before spinning anticlockwise continuously. Explain that using your fancy magnetic attraction theory.Anyway Jagjamin below me hit the nail firmly on the head. It would attract the closest magnet most, establishing a stationary position very quickly. If you fail to see why that is, go back to school. |

Yeah, its pretty obvious that it wouldn't work. Holding the magnet there wouldn't make it spin. The closest nanomagnet would be attracted the most, so it would stay still. |

DellSucks - you are correct, and keep in mind that it would take a significant amount of energy just to turn the hand magnet, because the repelling forces of the wheel magnets would be fighting against your turning motion. |

Oh, and hugemeister got it right way back on the fourth comment. There is another motor and a magnet wheel under the table. |
