Working Attraction Magnet Motor on Youtube!?

[Liberty]

If you think about what is happening when a magnet is placed near a piece of metal/iron, the metal reacts by forming a magnetic field opposite (so as to be in attraction) to the magnet and allow magnetic flux flow.  Therefore, the other end of the metal will form the same pole as the magnet.  As the magnet moves closer to the end of the metal, at some point the pole will flip, and the attractive force will be back toward the area that was travelled previously with the same pole as the magnet being formed at the beginning of the metal piece.  The next piece of metal will also form an attractive force, and there will be two attractive forces spaced apart creating a gap of equal attraction forces.  When metal is used with a magnet, it is simply a weak magnet that is formed that has a moving domain until it is easier for the flux to flow the other way through the metal (pole flip).

Correct. In this case, however, the iron pieces are asymmetric and when the flipping occurs the attraction to the more massive head will be greater than to the less massive tail.

Perhaps the devices that are made will help you to determine through experimentation, if that is what actually happens.

Wishing you the best success Omnibus and all the experimenters!
Have a good evening/day,

So far all the "replications" are to be ignored except for that of @klicUK. It seems the closest to the original.

Why? I didn't think mine was so bad.

Hello!

Have been following this discussion with interest since I first saw that video on youtube. Does anyone know what the stator is made off?  I just wondered if it might be having some form of magnetic shielding affect on the screws as the pass the magnets, i.e. preventing them from being pulled back. Just a though, although I'm sure some of you have already considered this.

Does anyone know what the stator is made off?

It had been stated by xpenzif either in this thread or on YouTube that is was aluminum although he did state the magnets where 'stuck on'. I speculated in this thread that it might be some sort of magnet alloy like soft iron. I also speculated that the hard drive platter that he had it mounted on might make a difference. Even though this setup seems simple enough there are a fair amount of variables that can still come into play. For instance it has also been shown that the rotor is off center and mounted at an angle. I am sure that this adds to the variables. Magnet strength is another. Xpenzif stated n45 but in the video he easily removes the screw driver which I think would be a lot harder to do if they were really N45. It boils down to this.... Without xpenzif actually stepping forward and providing detailed information and video feedback I fear that a working replication will be random at best and therefore a waste of resources to replicate at this time. As shown by the replicators here that have already tried without success it is not going to be as easy as it first appears even if it really did work to begin with. With the amount of time that has passed and xpenzif not writing a word I feel that this project is pretty much dead.

Later,

Hi M0thman, welcome to the club!

Actually, when (and only when) you see all the 'failed' replications you begin to think that, at last, the the Xpenzif 'machine' has a non conventional behavior as the magnets do not seem to impede the rotor.

Should we conclude that it is a fake, another bad joke?
I'm not (still) convinced about that.

Something could be hidden ("some form of magnetic shielding" as M0thman pointed out) or anything else (Hydrocontrol post). Perhaps, as Omnibus said, it is just a matter of fine tuning (and huge luck, of course  ).

That's why I'm continuing to glue these *?# screws.
