Ok...this is odd!! (shielding)

I have this medium sized ring magnet here at my office that I use as sort of a fridge magnet to hold paperwork to my metal cabinet. I also have this small candle that has a metal lid....bear with me here... The top of the lid is domed slightly. So I was sitting here on the phone and started figeting with the magnet and the lid AND some paperclips. I put the magnet on the inside of the lid and it stuck there VERY strongly. I thought "Hey... I'll make the top of the candle lid a paperclip holder. I then took a handfull of paperclips and put them on the top of the lid... guess what... they fell off... no magnetic power AT ALL!!!

So.. how is this candle lid able to sheild from anything sticking to the outside of the lid if it can stick so well to the lid from the inside? Whatever this metal is it sure as heck can sheild the magnet.

Sounds interesting

I just tried it here with one of those small 1.5 inch candle foil silver things, about 12mm high. Dropped the candle out but no difference.

Can ya post a picture of this material?

I would imagine that since the candle top was dome shaped, that the magnet would attract the paperclips from the outside, but not the inside is because of the air gap or distance between the magnet and dome.  From the outside, the ring sits right on top of the dome correct?  But from the inside, the ring would stop short of the top, because of the decreasing radius of the dome.  Make sense?

Sean - Hehe.. we spell our names the same! I too am a Sean.... Anyways wrong material... those little votive candles are in an aluminum cup. This was a glass candle with a metal lid with an ever-so-slight domed top... The magnet is roughly 2" in diameter with a ring thickness of 1/4"X3/8". So the magnet has about a 1-1/2" hole in it. I placed this dead center on the INSIDE of the lid... the concave side. If I had to guess at the airspace it left I would say no more than 1/8". The lid was non-magnetic on the other side...... not enough to pick up a paperclip anyways.

Konduct - I even tried doing the reverse with the magnet (placeing it on the top of the dome) and the same fact applied... the metal was non-magnetic on the inside of the lid as well.... whatever this lid is made of is doing a great job of canceling the magnetic field on the other side.

I'll take pics tonite... maybe a video as well... not sure if this is any kind of significant info.... just was interesting to me.

Tis the Irish way of spelling Shaun as you probably know LOL. So hence explains where the mad side of nature comes from LOL !!

Think I will understand more when I see your pictures.
I will try any material I come across to try shield these little devils!. Have placed most things from crystals to liquid gel in the hope of finding summit !!!
I have sandwiched various metals between various plastics following searls ideas and spent alot of time messing around.

Hey you got to keep trying, oneday someone might just stumble on something.
Have got some granite shavings coming this week as saw on a website somewhere that it does distort the magnetic field. Also interesting to notice that the infamous David Hamel uses granite as rollers on his Cone design.

Like I have said before, I am not a great one for playing with scientific stats etc, I just get my hands dirty and shrug my shoulders alot hehe

Look forward to the pictures.
