thank you tao !
interesting !
but for me ...
I need a simple solution to my problem, and copper shielding is !
FREEZER have given me the right way and the easiest for my 50$ F E motor !

best regards

Somebody posted this link in a recent thread about shielding, I couldn't understand anything of the information on the product/material's effectiveness. http://magnetic-shield.com

I thought I heard a long time ago that copper shielding, like the magnet-down-a-pipe braking effect, was where the Magnet's movement was interacting with the copper pipe as a closed (electrical) circuit; a loop or ring of copper. Lenz's Law.

It might be interesting to experiment briefly and see if its true. I don't have any copper on me right now, but I would join in
Perhaps try cutting a few different lengths of copper pipe and bend/hammer them into more manageable flat shapes to try as blockers?

Also, looking at photos of Thing's rotor, I have some ideas...
A copper pipe slows down the flow of magnetism so why not fix the magnets inside copper elbows on each end of the rotor? They are cheap enough at a plumbing supply shop. They come in different sizes and possibly angles like 45^o and 90^o. You could use elbows for each magnet.
You could orientate the elbows (or pipes) as you want them using shims to stiffen the pvc connection. (anything to help wedge the pvc pipe and copper elbows together, such as a roll of paper or foil)

To carry on the idea, you could replace the pvc rotor with a length of copper pipe with suitable copper end pieces, fixed onto the axle/bearings somehow. If I had that motor on my bench, that is what I would try next, thick copper elbows.

Wooden dowels may be used as spacers inside the rotor to keep the magnets apart, also maybe put magnet in blutack or putty to help it stay in.

A good balance is best for running any rotor. Using existing bearings are a good idea too, as NerzhDishual suggested, and vertical axis is more stable I think.
Use a flywheel, it will provide useable turning power as momentum increases.

Well, I played about with some magnets and copper pipe in my local DIY shop and am sorry to say, the magnets still interact with each other through the copper.
so much for that idea.
I know iron and steel can divert the flux, but they are far from ideal.

I will keep testing different materials as I encounter them, there is magnetic shielding out there somewhere !!

The ancient artifact about 1/4 down the linked page has magnetic shielding....

And on the big cup you can see a perfect inlaid star constellation also showing the Orion and other stars. And inside the big cup it is very, very magnetic and outside the cup nearly nothing.

Professional geologists are saying this is impossible because if a stone has metal particles inside the stone, it must be same magnetic from both sides.

Hi all !
I see there are lot's of good experimenters
but what you are trying to replicate is overstreched
and has very high sensitivity in order to work.
it is overhard to replicate
allso energy output is low
If you want something that works
  I suggest you turn to, with no false modesty, FDM by Igor Knitel
I'm experimenter in these waters for a long time and this is the most powerfull FE device I have seen
(MAHG from JNAUDIN is very good device but little complicated to make)

all the best

Can you make a link please Igor? Any search I do only gives one result, that is your comment here.
thanks
