See attached, the bars ends never are in the stator magnetic field or try to leave the field.

That's a bit of an hard one to accept readily. Because what would prevent the forces, causing the fanning effect, to push back on the elements you want to insert in between. I'm a bit double sided on this one, only an experiment can show the truth. Am I wrong to assume that you don't need all those separate element but two main blocks and one to slide in between should have the same effect? Then you would only need to show that the block indeed jumps in effortlessly.

We have had a video on our Youtube site for 6 months showing the element being pulled in between two elements that are in repulsion.

Broli,
Have you ever wondered why the two elements in a magnetic field stop repelling? The reason is the field between them is no longer compressed and the system has switched to attraction mode. This allows you to position an additional element to be pulled into the field between the two seperated elements.
Butch

Can you link me to this video please.

Sure, I will look it up and post a link, it's dark and was done by our member Lawrence but you can see the bar being pulled in. Mark may have done one also and we are looking for it.

That is a way to put it. The separation occours only under given conditions. If the magnet is relatively small compared to the two elements combined, the elements will not separate. I have played quite much with magnets in different sizes, and it appears to me that the elements will separate if the magnet is wide enough. The separation will find its equilibrium, the point where the attraction between the magnet an the elements are strongest.


How this position is suddenly switched to attraction mode, is something I quite not get...

Google "fanner for metal seperation" and read the theory of operation at the different sites.

I know about these separators, but I cannot understand how these switch from repel mode to attraction mode. When they are separated they are neutral. Maybe you had other idea about this in mind?

I have a video on Youtube that shows two 1" x 1" round grade 48 NIB magnets side by side, north next to north and south next to south with an iron bar on top and bottom with .005" air gap. The magnets can be moved up to each other with the slightest effort. But as you increase the air gap the magnets go into repulsion mode. The two bars are a closed loop circuit in a U shape. The magnetic field seems to fan out as it nears the iron when you increase the air gap. But if you keep the magnets up against each other the fields of the two magnets are compressed where this fanning out takes place. If you stop the air gap at say 3/8" and allow the magnets to repel they seem to stop when the fanned out field near the bar do not compress each other. This would indicate to me that the fanning effect is a result of the fields out side the magnet itself and takes place in the air gap. The two magnets behave the same as if the bars were part of a magnetic circuit with a single magnet in that circuit and the two magnets were replaced by iron cylinders the same size as the magnets.
A second condition to think about is what if two iron elements saturate and there is a large amount of field still remaining and it's path is between the two elements. Is this field available for pulling in an external element. Our test indicate that happens.
Thanks,
Butch
