Anyone tried this neodymium supplyer?
« on: June 16, 2005, 09:05:30 AM »

http://www.neomagnet.com/neodymium.html
Some of the claims seem a bit off and the prices are way cheap. For example 2" x 2" x 1/4" square n38 claim rating of over 200 lbs. But a 2" x 1" at 4 times the thicknes is only about 150 lbs. I checked a couple sites and they list the strength for a 2 x 2 x .25 n39 at around 45 lbs.  The price is $12.50 each. They are correct on their claim for their 1" x .5 thick round at $11 each

Might I suggest these people http://magnet4less.com/ Last order was from them ...never had any problem ...they are in the U.K. but i think they have a storhouse in the states ? and you have to order a minimum of 50$ witch is never too hard. I don't know though if it's only applicable to people overseas. check it out.

No, haven't tried them. If I can't get a certain magnet(s) locally I use HKCM (Magnet Monster) from Germany. They have a great selection, very professional, good packaging and also provide a custom magnet service. Unfortunately the postage charges are high but that's not due to HKCM.

Good prices and good service.  I have no interest in them other than that.

I got mine from magnetmonster:https://www.hkcm.de/index.php?language=en
What's funny is, they are also selling pdf patents of several magnetic OU devices, like the Adam's motor....

Edit: Ah I see NTesla already mentioned them. Well they are really professional as he said, and you can even mail them to make new shapes!

looks like the original posters link and site is dead. makes it look a bit fishy but could just be a server outage. I even turned off peerblock and everything else to make sure it was not an issue on my end.

something I suppose I may need to make a thread for, is a decent set of suppliers for Mumetal and permalloy in thicker than paper sheets, as I was looking and thought I should be able to find a source for say .010 thick at least sheets of either, but no such luck, thickest I could find was .005 inch (.0127mm?) really way to thin for my needs. so ...

Dude, have you watched the dates of the posts ?? 2010 of course it's dead nothing about freakin internet last more than like 6 months.
 
and just to say, if you can only find .005 and want .010 how about using 2 folds huh ? Either let some air bethween with shimes or add some none conductive material bethween the 2 sheets like cardboard. And just to say of what I did, see, experienced, research it's pretty damn a lost of time to try to shield one side of a magnet.
 
Just to say the magnetic field always get around or the other pole gets almost extinguish if I can say it like this. anyway one pole magnet do exist http://io9.com/5352998/physicists-discover-a-magnet-with-only-one-pole this is of course still in labs but you can buy magnets that are all ready capped in some kind of stainless steel shells at various strenghts and purpous look it up here: http://www.goudsmit-magnetics.nl/index.php?id=47 or just do a google search for
"pot magnets"
 
http://www.callowayengines.com/ an interesting website I stumbled upon while I was searching for pertinent info for you.
 
and to my knowledge if I remember correctly the less costly stuff to shield anything was like nickel (try to find a nickel quarter "25 cents" (there are websites that indicate witch is made in what at what year) and stick 2 same pole magnets on each side ...any material would repulse but in nickel it stick ...maybe there's something to do with this simpleness and the other thing is molybdenum so to hell with MUmetal that is waaaay to complicated and costly. (not to mention as soon as you bend it more than err 15 degree it's worthless because it looses it's protection in that angle) and you would need to reheat in a super complicated process) in other words you need to send them the exact mold you need and before you get it right you'll surely pass a few 100 000$ i'm pretty sure lol so the alternative is this:   
 
http://french.alibaba.com/products/molybdenum-price.html here's a place in question where they sell that sh*t BE CAREFULL if you buy on alibaba make sure you know the company you buy from and never EVER send money without some form of protection (read on the site for this) but hell I've seen sheets of the stuff sold 50-100$ per kilo and it's like 5 kilo minimum ...not bad at all nowaday. it's something worth investigating. i'm sorry the last link is in french it's because of my settings in alibaba but if you make a search on google for alibaba and molybdenum you'll find the same page in english...
 
I hope any of this was pertinent at all or slithly useful...  ;D
 
sincerly,

Wow i must of been drunk that night I barely understand what I wrote lol ...I can at least correct the 25 cents story.
 
-Some old quarters are made in pure 100% nickel to know witch are in nickel search on google for a website that tells what material has been used each year. It's around 1950 to 1980 more or less after that to 2012 it's steel at 90% + and using theses (25/10/5 cents made of nickel) you can either melt them (witch is illegal) or just do your best to do a layer taped together. To see the protection potential of nickel just take to small ceramic/neomagnets magnets like 1/4 x 1/2 max inches and stick both north poles facing each other on each side of the nickel quarter they will both stick on the quarter (of course the quarters are too small and it's a little difficult but they still stick knowing the repulsives force of theses little magnets I say it's pretty good so a bigger sheet should be better. Anyway there's alot of test to do with this and it would be nice to mount a site with these experience done and cathalogued... Just so we could refer noobs to it instead of them loosing their time doing it over and over again.
