Magnet force shield

Yes I've seen those vids by GotoLuc (tho I frequently fall asleep due to his voice, but that is an other issue).


As you seem to be into magnetic shielding, I'd be glad if you take a look at my shielding challenge in my "Searching for Buddy..." thread, tho, no strings attached etc. ^^

Maybe we can continue this topic on a general level about all aspects and findings about shielding.


I am currently confronted with that, once again ^^


Well isn't it that we all wish we had a shield that shields, but is not ferromagneticly attracted by the magnet it should shield? Not only because of the huge losses by the coghing.


So that is on mY wishlist. But how to achieve it. Let's see. Probably I could use several layers, alternating thick diamagnetic layer, thin ferrogagnetic layer, and by doing so, compensate the attraction. Only diamagnetics are very week, at least the available materials.


What diamagnetics do we have anyway? I got some pyrolytic graphite here, is there something better?

Yes I'm committed to doing good science.

Once bitten twice shy. 

I'm still sometimes in too much of a defensive mode, here (others are as well I think).
Many trolls are highly knowledgeable, and effective.
A two week long multi troll siege on ones topic is not much fun.

I prefer to keep my topics available to the non expert ( as I am non expert myself).
This presents its own kinds of  difficulties. 

I welcome expert advice, expertly, non expert presented. smile

Sinc you are committed to doing good science, I dare to present some good science about magnetic shielding:

http://www.magnetic-shield.com/pdf/how_do_magnetic_shields_work.pdf

I cite from this document: "Magnetic shielding materials re-direct a magnetic field so it lessens the field's influence on the item being shielded. Shielding does not eliminate or destroy magnetic fields, nothing does."

http://www.magnetic-shield.com/pdf/will_magnetic_shield_block_the_fields_effects.pdf

I cite from the document: "There is no known material that blocks magnetic fields without itself being attracted to the magnetic force. Magnetic fields can only be redirected, not created or removed."

There you find many good articles:

I hope you are not offended by some real science. You may call me troll, but you should read good science. It might help you to avoid years of useless work. Sorry for my trolling. I may look like an attack, but my intention is charitable.

I always hope for good arguments against well known science. But since I read the OU Forums I only have seen childish misconceptions. And the reason for this stupidity is because the "inventors" have not read the most simple science books or articles. One has to know what is allready known before going beyond.

Hey, maybe you've found a new use for my videos!


Doctors could use them to treat sleep deprivation

Well, Conrad, I've been there may years ago. But the simple matter of truth is that there's more to it, things beyond the standard teachings and simplifications for economical reasons.


You can shield a magnet with an other magnet in repulsion mode, that will no longer attract it. A combination of both can nullify that force. And that goes for both sides of the shield, independently. Then there are also diamagnetics, some new nanotube materials with cpmpetitive strengths may be soon available.


Yes, what goes in must come out, however, there may be a way to sneak out.
