You can get them from Tandy, of course, but also check out Michael's and Hobby Lobby. They have assorted sizes and shapes, even some rolled magnets- all found in the crafts or jewelry sections.

I've just received a shipment from amazingmagnets.com

They are amazing. They are some sort of metal covered ceramic. In the extreme, (as I tend to push things. They can break. I threw one at a metal object from 10 ft away, but that's another story....lol

But I think they will be perfect for all the projects.

Perfect timing Josh I just got my order

from K and J this week. Great little

ceramic magnets although as stated

afore they are brittle if you let them

slap together hard. I broke about

two the first day playing with them.

I ordered the sample pack and the

six different ones used for clasps on

necklaces and bracelets. I got my

order in two or three days.

thanks all for the help.

I need thin magnets and I have never seen any at Tandy have any of you and am just up in the night.

Try Walmart craft department for your magnets. They sell round in couple sizes and also couple widths by the roll. I bought a roll cause I had to make a couple neck sheaths for miniture knives. They are easy to work with and can be cut to fit with just a pair of shears.

Hobby Lobby sells purse closure magnet sets. I think that's what you're looking for.

I use these from Wood craft. They are very strong and thin.

Josh,

I doubt you will find any thinner than these.

They are 1/32 inch thick.

K J Magnetics has lots of variety. . . if you go to Ebay and search for "neodymium magnets" you will find tons of variety of different types. . . you can narrow your search to "neodymium disc magnets" and then you'll be able to find the thin ones the size you want. . .I use them on lots of small cases, etc sewn under a thin piece of leather.

Those are a little thinner than the size I use from woodcraft. I have a woodcraft store near me, so I can walk in anytime and don't have to wait on shipping. The 1.5 mm thick is about 1.8/32" or roughly 1/16th of an inch.

I went to Michaels looking for small magnets to make a name tag with and found all sorts of magnets. From small circular ones to ones that are in long strips that can be cut to length to a whole sheet.

Thank for the help guys.

Rare earth magnets like Neodymium and Samarium Cobalt are extremely powerful. Be aware that they are pretty fragile. They tend to be very brittle and subject to chip or crack especially if you drop them or if they pull something hard to them too quickly.

When it comes to power, they put ordinary magnets to shame. A very small neodymium will outperform traditional magnets many times their size.

I have a question about magnets, will they cause any problems such as data loss? Such as a case for a mp3 player or a cell phone data card. Jordan

Not sure. I remember at one time that a magnetic money clip would kill a credit card. That's not the case anymore, but I can't speak for the new digital items.

Fortunately, most modern storage devices, such as SD and Compact-Flash memory cards, are immune to magnetic fields. "There's nothing magnetic in flash memory, so [a magnet] won't do anything," says Bill Frank, executive director of the Compact-Flash Association." magnet powerful enough to disturb the electrons in flash would be powerful enough to suck the iron out of your blood cells," says Frank.

The only magnets powerful enough to scrub data from a drive platter are laboratory degaussers or those used by government agencies to wipe bits off media. "In the real world, people are not losing data from magnets," says Bill Rudock, a tech-support engineer with hard-drive maker Seagate. "In every disk," notes Rudock, "there's one heck of a magnet that swings the head."

So to wrap things up you would need very power-full magnets to do any damage.

Rare earth magnets have the kind of power that you are talking about. A neodymium disk 1/8" wide and 3" in diameter will pull 40 pounds. A 3"x1" disk will pull 255 pounds. That is some huge magnetic power. I would not get a rare earth magnet anywhere near electronic components unless you are certain that a powerful magnetic field will not affect the component. Better to be safe than sorry with these things.

[jbird]

I am not saying one that can get any were close to that amount of power just enough to close a lid on a case, i think you start getting those kind of mags around electronics you will start pushing the envelope.

Josh

just got my shipment of mags they are perfect.
