The Best Refridgerator Magnet Money Can't Buy

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.

Step 1: Find an Old Hard Drive, and Take It Apart

For this job you'll need some torx drivers of various sizes (5.5, 8, and 10 were what I needed). Just keep taking out screws and peeling back labels until it's all in pieces.

Step 2: Make a Little Wire Handle

I used some 18 gauge solid core wire I salvaged from a vacuum cleaner motor... you can use what you have on hand.

Step 3: Stick Stuff to the Fridge!

Speaker magnets work well too, but I got tired of trying to clean the metal shavings from the rivets off the magnet. Does anyone know a better way to take speaker magnets out?

    If you have a non-functioning microwave, there is an incredibly strong pair of magnets inside. I think the part is, oddly enough, called a magnetron. If you do decide to harvest them, please be very careful. I'm sure there are electrocution hazards within the microwave.

    Don't touch the pinkish ceramic stuff in the magnetron (especially if it's broken), it's toxic.

    Beryllium oxide. It's mainly found in older microwaves. I think Wikipedia has some details on it. (Wikipedia was pretty small back when I made that first comment!)

    Ya, I did this, I had a drive fail on me just a couple months ago. That isn't no lie that magnet is a pain to pull off the fridge. It sure does hold up a heavy calendar with out sliding down.

    you would have if it was a CRT one but with LCD and TFT, why ? for the reception ? normaly, until the magnets don't move around, it will not change too much ! (in case that the TV as an internal antena), but if connected to wall, what problem can you find ? please tell me i am curious ! really !

    HEY YOU

    Sometimes the HDD magnets are attached to a base that is screwed to the housing with a M10 cap screw that you can use to force it off the base, but you could also use it to attach a convenient handle.

    I would also coat the magnet to avoid damaging the fridge door.

    Cheers
