"Turn Off" a PM... Strategies

[CANGAS]

Hi everybody.
I'd like to discuss the possibilities in turning on and off a permanent magnet in general.


It turned out, the inability to do that is the main problem of many PMMs. So what we need is the "egg of columbus".


Let's list the options we're already aware:
(they all seem to require an external energy to do the "turn off" job, not sure about the close-loop deflection tho.)


-Electric Magnet impulse in opposite polarity.


-Heating up over Curie Temperature


-Mechanicly/dynamicly move away pm or iron.


-Mechanicly/dynamicly "shield" pm field


-close-loop pm with an external, deflecting pm or pm chain.


Any further ideas?
Thanks.

Any further ideas?


Ruger Super Blackhawk, 6 magnum hollowpoints, dont initiate your experiment near unprotected bystanders, and, not where it could burn your house down.

Hey, Jack, I'm not joking. Dont start something you cant finish.

Let me splain. Suppose your invention really does work and, out there in Open Source, some angel picks it up and manufactures it and sells them like wildfire. And further suppose that a typical rich person manufacturer does not know used beans about Physics and simply perfectly follows your sketches on the back of an envelope. Your information must have some kind of an absolutely fail-safe escape mechanism, perhaps a brute force solution, to perfectly guarantee that your lovely device will never ever be responsible for injury, death, or property loss.

Of course, by "turning off a PM " I meant to neutralize, compensate or whatever is required in order to eg. reduce the attraction for a moment. And of course the goal is to do that in a free way. I don't say OU, because we may use any source of energy that can be tapped for free, eg. athmospheric pressure changes. Sunlight or Wind etc. is out of question or let's say is covered by the simple creation of an opposing e magnetfield listed initially.


I am more interested in micro-macro coupling of spins, also probably manifested in certain geometry, as in Schaubergs works about streams. Another sample for macro coupling of nuclear spins is the vortex of a kitchen sink, that is oriented to the earths axis. So quantum theory and special materials with extraordinary features like eg. high diamagnetism may be interesting. Graphite is highly diamagnetic and may cause the same kitchen sink vortex torque or spin in relation to gravity and magnetfield, where the magnetfield of a pm can be a catalysator, compared to the one of the earth. Well, interesting anyway.


When I tried to transmute  graphite powder to steel by shocking it with 30vdc, it became partially highly diamagnetic, so particles would jump away from a PM several Millimeters, not shure if the unshocked powder performs the same way.



BTW Cangas, did you by accident type in the wrong browser tab? Looks more like a Gunnie thing, or what was that bizzare thing about?  Looks like, some scientists discuss magnetical properties, when suddently somebody opens the door and yells "Pepper!". Please explain.

You really need an "explain"?

OU would not work like normal everyday reactions that are often damped before they can become runaway. Or very violent.

Do you really need it to be explained to you how a genuine OU activity will be beyond the purview of conventional Physics to predict and therefore  its safe containment cannot really be predicted?

You mean it will run faster and faster and finally explode?
Well thanks for the warning, but this is known. Besides, I,d be glad to overcome the mechanical losses and if required it wouldn't be so hard to slow it down, certainly easier than to prevent a certain mass of plutonium to instantly melt down...


What I am trying to say is: I would like to see contributive postings, like ideas on how to "turn off a permanent magnet for a moment". Thanks for understanding. I would also like to discuss Graphite in this context, is there anybody with experience regarding Graphite, or pyrolytic graphite, and most promising in terms of diamagnetism: diamonds! And also the sink vortex phenomen, that is definitely a magnetical thing, due to earth axis alignement, (that it spins in the other direction on the southern hemisphere).


Anybody?

I was not going to mention this because I have not yet fully confirmed what was going on but I will try to explain it anyway.

Thinking that maybe a large thin magnet may shield some force of the interaction of two magnets by letting them get close before they exit the large magnet, I found the poles that attract seem to travel through the large magnet and thus the idea did not work.

I then thought that maybe two large magnets opposing each other could solve the problem, but still the attracting side to the large magnets seem to reach into the center of the two and repel the other approaching magnet.

So now the strange part:

In the emulator, I placed a very thin iron sheet between the large repelling magnets hoping to short the smaller two approaching magnets and let them ignore each other until they reached the mid point. Then I found this huge attracting force from that very thin sheet of .001" thick iron.

It seems the thin iron sheet directs the compressed field between the two large magnets with a huge force but the iron sheet itself is too thin to be but attracted with little force.

So at this time, it seems possible that one could direct a very large force by rotating that very thin iron sheet within the compressed field of two large magnets.

I've had this on a back burner for some time now so I thought this a good time to throw it out there.
