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?
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...

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.
"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. (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".
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.
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..
