Title: magnetic shielding misconcepyion
Post by: mattlt on August 12, 2008, 08:31:37 PM
Hello
first timer here
Has anyone thought of reversing the thinking that a magnetic shield is realy a superconductor?
I purchased a lab kit from
www.magnetic-shield.com
the shielding is actualy a superconductor (high permeability) the magnetic "force" will follow the path of least resistance.
I am working on a magnetic valve using this alloy and will post results as I can prove any outcome.
Hope this is helpfull

Greetings mattlt

 And welcome to the forum. I believe you are talking about mu metal. It is some interesting stuff and very expensive with 75% nickel in it. From what I understand it can only stop week magnetic fields. Not like a rear earth magnet, or even a ceramic one. There has been a fair bit of talk on the forum of shielding, but I would like to here what you have to say.

Hi AB
the material I purchased is netic & co-netic.
it was available in a lab kit for I believe I spent $150. it comes with allot of specs as well for those more educated in this field.
...oersteds vs. flux density
simply shielding one side of a magnet and hoping for perpetual motion didn't work. I achieved an approximate ratio of 4:1 for repelling distance, but the total force was the same. on a wheel/stator setup, with one side of the stator "shielded", the rotors approach got allot closer to the stator, but required the same force to pass the gate.

expirament with thoughtful results:
two paint sticks taped together at one end (hinged) and two neo disks in repulsion at the ends. A cardboard housing was made to keep this expirament manageable.
when I start to introduce the shielding between the two magnets, they both move towards the alloy.
note that if the alloy is not right in the middle, one magnet will take preferance over the other.
when the alloys is removed, of coarse, the magnets spring back away from each other.

the permeability of the netic alloy is over 5,000 and co-netic nears the 500,000 mark
this is at just over 1 oersted for the netic, and just under .01 for the co-netic
I have also played with compressed helium as per my googling and had no luck.
what do you think of a crt workbench idea? tv flliped image side up, cover with a work surface of plexi and watch the field lines so as to work with those forces in visual representation instead of just magets marking their north and south.
Is the effect of magnets to crt misleading? or is it a viable option?

thanks for the long read.

Have anyone ever studied the effects of lenses on the magnetic fiel

Omg please check this video.  The best magnetic shielding is spin.  This video shows 55lbs magnet losing its attraction for e to a steel disk due to spin. Enjoy
