Picture of Tool demagnetizer
Aren't you pissed off when you pick up your screwdriver and a screw gets stuck to it??? I got tired of that and decided to build a demagnetizer out of an old transformer which was pure crap (i mean the transformer was crap)

Step 1: Materials and tools

You need only 3 things to do this Instructable:

Old EI transformer which you don't mind destroying it
Hammer (the must have tool in every workshop :D)
20 minutes of your precious time (5 minutes for reading this Instructable, and 15 to build the demagnetizer)

 what voltage are you running this on? i hope it isn't 230(or 110, depending on where you live)

its 220V, but it cant kill you if you are put the connecting wires on a side...

 you're seriously running 220 trough alligator clips!?!? the least you should do is add some heatshrink around that, this thing's a deathtrap! but seriously you should NEVER EVER have exposed mains voltage, even if it can't kill you it will hurt like hell, and if you grab it in the wrong way it can and will kill you, when touching mains your muscles will contract, causing you to clench anything in your hand, meaning you can't actually let go until it's plugged out,

i am using alligator clips when i was testing it, and then i took that picture. I don't leave anything to run more than minute with alligator clips. i have connected other cable after i test the demagnetizer....

I actually like having screws stick to my screwdriver. Take a powerful magnet and stroke your screwdriver about 20 times on it and voila! free magnetic screwdriver.

sometimes i like my screwdrivers to pick up screws, but i dont like when small bits of metal stuck to my gauge meter, or on any other tool except screwdrivers, i pointed screwdrivers because they are mostly used, you can demagnetize every tool that you have in your workshop that doesnt suppose to pick up metal...I hope you understand what i mean.
