Firstly You'll have to take apart thr hard drive, now hard drives weren't mean't to be tampered with so you'll need a special six sided srewdriver. If you don't have one an eletric drill will do nicely. Firtly remove the screws that hold the cover on. Then break the seal. You should see a shinny metal disk that looks like a cd-rom and a little arm over the top of it the arm is called the head. Our magent is under that. We are not looking under the end were it reads the disk it under the other one. There should be a metal plate that the end of the head disappears under. unsrew and remove it. You should now see the head expossed now remove the head, the head may also have a screw underneath so check that too. Remove the head the thing that remains is the magent, if it has some screws remove them and there you have a NIB magent. Note that the magent is attacted to a backing plate you can remove it if you wish or leave it on, I leave it on because it makes it less likely to snap. Ps: Look for older drives as they have bigger magents | ||

Remember that disk drive magnets are usually only about 20 to 35 MegaGaussOersteds, and that the Gauss Rifle and the Levitation projects really benefit a lot from using the 48 or 50 MegaGaussOersted magnets we recommend. The rifle will shoot faster and farther, and the levitation will be higher. | ||

Thats ture, but isn't that only for modern drives? Old 5.25" ones have really powerfull magents. | ||

35 MGOe seems really powerful until you play with a 50 MGOe magnet. | ||

Yea i guess so I'd really like to get a hold of a few of them but I'm not aware of any retailer that sells them in my area, and I can't buy them online since I don't have a credit card  | ||

try http://engconcepts.net/ You can order them via a money order, personal/business check, bank check, purchase order (maybe), paypal, or wire transfer (Western Union). He is flexible. He does this for fun, so usually gives you a discount for varied/large orders (like free shipping, or some extra surprise magnets). His magnets are not as high-quality as scitoys, but very affordable. He has up to N50 (but most are N40-45, some are N35 or lower so beware). I've ordered with him several times and highly recommend. I have been able to do levitation with his magnets using PG, bismuth, regular graphite, and galena. | ||

You can buy from anywhere online that accepts mailed payment. | ||

I got my magnets from k&j magnetics (http://www.kjmagnetics.com/). They have a wide variety of shapes and sizes. They will even do custom orders, but it costs $150 minimum per shape. Their shipping rates are good, $4.50 flat rate, and it only took three days for mine to arrive. Speaking of shipping, how do companies ship those huge hand-crushing, electronic device-destroying mags? do they just ship it in the center of a large box or is it shielded somehow? Or do they just put a warning sticker on it? I could imagine some poor mail carrier trying to deliver a small box that takes over a hundred pounds of force to get it out of the delivery truck. And then once it's out it's got several other packages stuck to it, but they deliver it anyway because let's face it, mail carriers are lazy. Hmmmm methinks this could be a way to get free stuff. Just buy one of those strong mags and keep shipping it to yourself and see what sticks. Maybe you could even get an i-pod, or more likely a ruined i-pod. | ||

They "shield" the poles with steel. Well, they don't really shield the poles... they conduct the fields into a tighter loop than the poles form through the air. Well, that's not totally accurate either. Lets just say, putting pieces of steel strategically at the poles causes a reduction in field size and strength. After that, you just have to put them in a big enough package so that no point of the surface of the package (or more usually, a measurement taken a certain distance from the surface) violates listed magnetic item shipping restrictions. They are much more restrictive for air shipping than ground. I think anything strong enough to hold a paperclip to a box would be such a violation. When I ordered 6 cubic inches of NIB (12 1x1x.5 squares), they came in a smallish (~12" cubed) shielded box. Sidenote, these magnets are very strong at the surface and a short distance away, but their fields drop off remarkably fast. A very large and weakly magnetized piece of steel would be more danger in proximity to computer components than a tiny NIB of equal lifting power. That isn't to say that you can take a NIB and rub it against a floppy disk or monitor! But they aren't too hard to ship. Just need bigger heavier boxes with sheets of steel. I've shipped some 1" N42 overseas by air with no probs, using wraps of steel and foam. | ||

Dang! I thought I was on to something. |
