The magnet from a 3" hard drive probably spans about 1.5" or so -- so
you'd need half a dozen.

You definitely want to intercept a bunch of dead drives on their way to
the dumpster -- the magnets aren't the part that gets dead, and the rest
of the drive is throw-away (unless you want a bunch of mystery metal as
feedstock for some really questionable castings).

I was buying damaged hard drives from a local computer shop for $.75.
There are about ten different configurations for magnet shape, how
they are attached to the case and the layouts. Some of the magnets
will be have the poles on opposite ends and others may have the poles
through the thickness.

I saved magnets from them and use them to hang tools off of benches in
my shop.
The small hard drive motors are fun to tinker with also.
The circuit boards at my local recycling dealer are worth about $1.25/
pound and one board usually weighs about 5 to 8 ounces.
The Die cast Aluminum the case is made from is only worth about $.30/
pound.
A sharp knife and a good screw driver with various heads are all you
need to disassemble the drives. Some of the IBM drives will require a
special tool that costs @12.00 at Radio Shack. I can strip one down in
about five minutes now but when I first started doing this it could
take as long as twenty minutes. It took so long because they are all
put together different and figuring out what tool and how may take a
while.So I would say if your time is worth anything it will be cheaper
to buy your magnets from E-Bay and pay $10 or less. But if you have
time to spare it is very interesting tearing these things apart and
figuring out different uses for the various parts.

Have fun,
DL

Those magnets are small and not very good for your purpose as they are asymmetrically magnetized.

Nah, just where we look for arrowheads, there are a lot of gravel bars and
pockets between the sand dunes exposed by erosion that have some interesting
small rocks in them, and a magnet would find one in a second. So, while I'm
there, it would take no more time to sweep the area with a strong magnet. I
have seen the drag behind huge coil those boys use on Meteorite Men, but
they use it on flat plowed Kansas farmland. You need it close to the
ground, and that is difficult to maintain unless you have absolutely flat
ground, and that isn't anywhere I know. Those guys found one loaded with
olivine on a recent show, and computations on the gemstones in it approach
$1million. The White Cliffs (Castle) area in NW Arizona has a strewnfield
of Martian meteorites, and one as big as a matchbox may bring one million.
But looking at them, they look like any other rock to me. They're (IIRC)
not highly magnetic.

My sister has a large, blue-plastic coated magnet from her stint at
Mercy Hospital (clerical) in Sandy Eggo 3 odd decades ago. I don't
think they use them any more. 3.5" dia, 1/2" thick, 1" hole in the

Hard drive magnets are for the seek motor, have a range of a few
millimeters.
What you want, for exploration, is a magnet with the poles far apart.
It matters not at all what the diameter is, you need to specify the
spacing
of the magnet poles instead. Easier, though, to just use a metal
detector.

I've owned a metal detector since 1980. Swinging one all day is tiring. I
do have a White's, but for quick, down and dirty hunting while hunting, I'll
see what this magnet will do before I take my metal detector out there and
swing it for eight hours.

Nah, just having something I can swing an inch or so off the ground in
gravel banks and flat areas that have eroded gravel in sandy areas. Some
areas have black sand, which is ferritic sand, occurring where gold is
found. A magnet would get fouled with that stuff real quick. But I'd keep
all bigger pieces it picked up to check at home.

A little tick to keep your magnet from getting plugged up it to wrap
some Saran Wrap around it. When the clump of magnetic material builds
up to a certain level just wrap the Saran wrap around it and put it

You must have one helluva pickup truck! Some of the rights of way are very

I was going to write something like that, but decided it really didn't
apply.

We lived East of Seattle and North of Issaquah on the Pine Lake
Plateau. What is now Sammamish.

The "plateau" is all glacier till. I tried to check out the soil/rocks
with a large, very strong magnet, and picked up great gobs of stone
particles. Probably the remains of your black magnetic rock.

Also dug out a several pound rock that was entirely iron oxide (rust).
Strangest thing I ever saw. Broke it up thinking there was an artifact
in there somewhere, and it was rust.iron oxide all the way through.

better might get excited.

I was going to write something like that, but decided it really didn't
apply.

We lived East of Seattle and North of Issaquah on the Pine Lake
Plateau. What is now Sammamish.

The "plateau" is all glacier till. I tried to check out the soil/rocks
with a large, very strong magnet, and picked up great gobs of stone
particles. Probably the remains of your black magnetic rock.

Also dug out a several pound rock that was entirely iron oxide (rust).
Strangest thing I ever saw. Broke it up thinking there was an artifact
in there somewhere, and it was rust.iron oxide all the way through.

Some of the rarest meteorites found have been found in Antarctica. Almost
every dark metallic object in the ice is a meteorite.

Howzbout one of these? http://www.google.com/search?q=cow+magnet

My sister has a large, blue-plastic coated magnet from her stint at
Mercy Hospital (clerical) in Sandy Eggo 3 odd decades ago. I don't
think they use them any more. 3.5" dia, 1/2" thick, 1" hole in the
center, aqua. Jus gawdjus.

What's with the iron-containing ites, anyway?

I guess some of them have high nickel content, going off for a metal
detector, but not being drawn to a magnet.

Steve


Nickel is magnetic also.

So are some bronze metals too.

A plastic bag is less messy - when the outside of the bag loads up,
reach into it, grab the magnet, and turn the bag inside out, with
the schtuff inside it. :-) (that also works with dog poop. ;-)

Your dogs poop is magnetic???????

What are you feeding him???

I need a bunch!!!

And how does he keep a dog inside a plastic bag?

Just in case you guys aren't joking, you use the plastic bag as if
it's a glove, THEN turn it inside out, around the poop, with your hand
now on the outside.

But you guys aren't _really_ that obtuse, are you?

Hopefully, you turn the bag inside out, grab the poop, invert, and
then SEAL the stinky, icky thing before disposal.

That's for the 10% of dog owners who bother to pick up the crap. Grrr.

Are you talking about dragging the magnet across the ground, in hopes
of attracting these magnetic shards, or just using it to check them
when you think you've found one?

If you're out hunting for meteorites, you might consider one of those
"metal
detector" projects. :-)

Nah, just having something I can swing an inch or so off the ground in
gravel banks and flat areas that have eroded gravel in sandy areas. Some
areas have black sand, which is ferritic sand, occurring where gold is
found. A magnet would get fouled with that stuff real quick. But I'd
keep all bigger pieces it picked up to check at home.

A little tick to keep your magnet from getting plugged up it to wrap
some Saran Wrap around it. When the clump of magnetic material builds
up to a certain level just wrap the Saran wrap around it and put it
where you want.

Large bag, or small dog. But the real trick is to put just a tad
bit of bacon fat at the bottom of the bag. That will attract the dog,
making it much easier to get it inside the bag in the first place.

Oh, and twist ties usually help.
