@gravityblock . I do hope you will reconsider your decision to disappear . The forum needs original thinkers such as yourself .

I don't have it all figured out, but I'm not going to ignore something or suggest it should be sent to another thread that may have importance to this discussion. This is a waste of my time.  Can't even get people to give something a little consideration.  Closed minded people.   I'm logging off now.

Actually I did give it some consideration, unfortunately I don't have the link handy but I believe on the magnetec (creators of nanoperm) site they mentioned their line of laminated cores or tape cores.

I went back and looked at "There are no electrons" By Kenn Amdahl (required reading if you've haven't yet, can't recommend it highly enough) because in the section regarding EMF he talks about the "iron losses" cause by a soft iron core. They're due to eddy currents within the body of the solid toroid. One of the ways around that is my creating "laminations", thin coated sheets of steel or iron. Each sheet is thin enough to suppress a lot of the currents (they can't move up or down much, just horizontally) If you break open a brushless DC motor, like say in a computer fan, you'll see that the coils are wrapped around these laminations.

Using a magnetic tape would be an example of a laminated core. Unfortunately it would be laminated only horizontally, along the circumference. What might be really interesting is if you could create a core that started as a wire ring, and then was progressively coated in ferromagnetic material, so it would be like a donut-shaped gobstopperâ€"radial laminations. That way you'd suppress eddys across potentially three dimensions.

Something else I found that was interesting is that magnetic tape actually predates modern ferromagnetic cores by a few decades. The cores that are widely in use now are sintered (compressed, like in a pill) from a powder that is so fine that each grain actually represents a single magnetic domain. The implication is that a lamination into itself. I would imagine that a nanoperm core has literally zero eddy currents.

So GB, I'd say you may be right about the effect being related to eddy current cancellation in the magnetic tape. I would encourage you to get some ferrite cores and try your experiments on them as well, you might find that they respond in the same way.

I understood magnetic saturation to be describing a situation where all of a core's domains are aligned in the same direction. I don't take that to mean that the core will at that point be "immune" to an external magnetic field, but that it's engaged with the field to its maximum. Externally a saturated core would appear to the world as a permanent magnet…right?

It's not like the core is saying "Nope, no more, I'm full, move on, no magnet here!" and the magnet gets all its field back. It's that the core is becoming as close to a permanent magnet as it can be, accepting as much of the interacting magnetic field as it possibly can. Any remnant field from the interacting permanent magnet would then seek out any other available permeable material.

I had less than 30 people look at the video on the magnetic recording tape showing magnetic viscosity.  I'm sure more than 30 people are reading this thread.

Other ferromagnetic materials have the same effect as the magnetic recording tape in the video.  When will you guys ever notice something important after seeing it for yourself.  You have to do more than just watch videos.  You must study, examine, and analyze every part of it. 

In fact, I haven't seen any videos on replication attempts in a long time.  Most of the replicators have left this thread.  The reason is simple.  They have tried what has already been tried and were unsuccessful, so they gave up.  Stop doing what has already been tried, and that goes for near saturation also.  Stay on the linear portions of the core material and have the rotor magnets ride this light repulsive force.

GB,

I tried using a similar concept with ceramic magnets and a neodymium magnet to magnetize the ceramics in whatever direction you might want. I was unable to find a method to use the principal to any advantage.
It still takes work to overcome the previously magnetized direction and again work to separate the two after magnetizing it in a new direction.

I don't see how this effect can be used to any advantage, unless you have some other concept.

Hi Gravityblock

I like very much your tape idea and  of course  when something interest me,  i can not prevent me to test it

very interesting results

the tape is a TDK video from an old video recorder

But what is really intersring is that you can manipulate the orientation of the magnetic station at will

i could changed the north and south pole by simply applying the strong magnet 1 second at any place and the tape stores the pole

I could also make 4 poles on the tape.

Woohoo  very inteersting

and bravo GB

It was Wesley Gary and he called it the neutral zone. I studied his work many years ago, and I also came to the conclusion that this motor is working on the same principles.

Hi guys,

@freeorbo, Oc and Gb -

The effect you describe is this similar to that which the guy that made the "GARY" motor found.

Something about a NULL zone ?

Don't remember the specifics, but I do remember reading this in a document of his.
