Hi all.
Had a hard drive go dead on me so took it apart
because I had heard something about magnets inside.
So I got 2 c shaped mags out of it.
So at the moment, "My mind is a raging torrent, flooded
with rivulets of thought cascading into a waterfall of creative
alternatives."

Question is, any simple ideas on how to use these powerful little buggers?

Good for making a moving iron speaker, if ever you want one. Which is
unlikely.

Useful for concealed fixings of cover plates and panels.

Stick them on your fridge?.......Fridge magnet....sorry, its late and my

They snap together very fast and hard. Some kind of DIY castration unit?

I used one recently to extract a small pin from a toy from between the
kitchen floorboards. The pin had dropped right into the groove. The magnet
also pulled out three rusty nails.

So - tie a piece of string to your magnet, keep it in a small plastic box,
and then in your toolkit. You never know when you need to pull some rusty
nails from a floor...

well the trouble is they aren't. Powerful.

However if you replace them with a load of neodymium magnets and rewind
the stator you can make a nice little model aeroplane motor..

You are kidding, right? You do know that these little flat magnets used with

You can also find them in the lens assemley of old CDROM drives.

Toys?
Saw an interesting use for scrap rare earth magnets the other day. Break
them up into 6-12mm chunks. Rumble them until the edges are well rounded.
Polish them with some sort of ?paint/finish? Sell them as toys. Well
Clare bought some to keep the kids at school happy.

neodymium magnets


"If swallowed, neodymium magnets can cause lethal conditions by
joining up inside the intestine."

Neodymium magnets should always be handled carefully. Some that are
slightly larger than the size of a penny are powerful enough to lift
over 10 kilograms. They are hazardous; able to interfere with
pacemakers and implanted heart devices with deadly consequences [1].
An NIB's magnetic force increases with the size of the piece of
ferromagnetic metal and larger neodymium magnets can severely pinch
skin or fingers, or even break bones when suddenly attracted to a
magnetic object. Operating a large neodymium magnet close to smaller
magnetic objects (keys, pens, etc.) and larger magnetic surfaces
(radiator or a car, for example) can be dangerous if the person is
caught between the magnet and the magnetic object or surface.

I use one to reset the max/min thermometer in my greenhouse, and the
other is taped to one end of a 4ft bamboo pole, for rescuing dropped things
from behind other things.

It's useful to cover a pickup magnet with a strong plastic bag. When it
gets all hairy with filings and bits of steel wool (that's when, not if)
you can remove the bag by turning it inside-out, leaving the magnet
clean.

(There's a 6" length of heavy copper wire
glued into the other end of the bamboo, for making custom hooks for
retrieving things.) I call it my "stick of picking things up".

Snap - a 30ft fishing pole with a copper wire S-hook on the end is my
"stick of getting things down out of trees."

Find the main water feed pipe to the house, position the magnets on
opposite sides of the pipe so that they attract each other, and tape
them in position.

You can then test the theory that they reduce the build-up of limescale
without forking out twenty quid or so for the privilege.

And that really does happen doesn't it. I found the distance things
jump / slide / roll / jamb / stick is directly proportional to their
importance / irreplaceably ... (probably someones 'Law') ;-)

Yup. I droppped a holesaw down the back of some cabinets. Used a magnet
on a stick..and lost that too!

Fortunately I have a few scrap electric model motors..the magnets of one
were enough on the end of a bit of kevlar fishing trace to recover both
items..

I use a nice little strong magnet on the end of a telescopic rod (rather
like a radio aerial). Standard item from some tool shops, and pretty
cheap.

i've not seen it but I have read that you can do nice tricks when you
move them near a piece of copper (or oethr conductor). Drop such a
magnet down inside a copper tube, or beside a copper sheet, and it
falls very slowly because the eddy currents it induces as it falls.

I also have recently stripped a faulty HD Drive (did you keep the nice
screws?). I used one to magnetize one of my posidrive screwdrivers. I can't
think of any other uses, at the moment.

So where would you get gadolinium from? Couldn't see any at Screwfix.

Would they be strong enough to produce magnetic phosphenes?

You get curved (parenthesis shaped I suppose) rare earth (neodymium iron
boron) magnets in the voice coil. Handy for stringing cables round the
lab in work as we've got steel framed partition walls.

just used a pair of much smaller ones to stop the letterbox banging in
the wind - a decent hold shut even with a 2mm gap in between them.

We were somewhere around Barstow, on the edge of the desert, when the

saying something like:

opposite sides of the pipe so that they attract each other, and tape

No, to make sure it works you must post the twenty quid to me and I'll
send you a leaflet telling you it works.

That way you get the full buying experience.
