“Using the magnets from a dead 3.5″ HDD and a piece of wire, I made a super strong refrigerator magnet. When I say super strong, I mean this thing will hold up anything I ever wanted to put on my fridge.”Link.

    now complete with misspelling in the title!

    I beat you by a ton(almost literally). I took two of the magnets(strange crescent shaped ones) out of my 5.25″ full height Micropolis(thank goddess they’re defunct now) and did the exact same thing. I put my 15″ cast iron skillet on my refrigerator with one of them and it not only held it to the fridge, it wouldn’t let it slide. I have to use two hands to hold the thing so that’s not an easy feat..but a great conversation piece. The two magnets got too close to one another once while my fingers were between them…would have broke them if I’d been any slower.

    I use these all the time, but you need to be cautious. In addition to being extremely powerful, many of these magnets are fairly brittle. Their own attractive force can pull them into steel hard enough and fast enough to shatter them into a kerjillion needle-like shards. The material from which some such magnets are made is also somewhat toxic, which adds to the hazard posed by the shards.

    I drip mine in a couple coats of Plastidip, more for the sake of the fridge than the magnet, but I can see the shattering issue being solved with this too.

    Hehe, I am a colledge gradguate.

    And FYI, money can buy these…all day long. Search for Neodymium, rare earth magnet, NdFeB.

    I paid for the hard drives I took the magnets from, so technically my money did buy them… :-)

    I use a couple of these to stick an old 3.5″ floppy to my refrigerator at work. It’s fun to see how people react to that. :-)

    At home depot and Lowe’s they have a liquid rubber coating. They keep it by the spray paint. You can use it to dip the handles of your tools. I bet that would solve the fridge scratching problem nicely.

    I have one of those white metal security doors with perforated metal that doubles as a screen. Some spot welds broke loose in the center, but one of those magnets holds the screen to the little iron bar behind it with a fair amount of magnetic force. Handy little repair item, although some people ask about it sometimes.
