Anybody know how to de-magnetize metal?

[Den]

I got around to pulling one of my old blue/white XL-12's out of storage about 3 days ago.

The guide bar and chain on the XL-12 are like a giant magnet !! It's seriously strong.

When I took the bar/chain off, I unknowingly laid my best screwdriver on the bar for a second... now its magnetized.

Is there any way to de-magnetize my screwdriver, as well as the bar and chain?

Snap-on,,used to sell a small thing,,to magnetize screwdrivers and such,,and by running on the other side,,it would de-magnetize it....

Lots of ideas if you Google it - too much to copy here.

Simple things, like your screwdriver, may just require rubbing it against a strong magnet.

You need an AC field. If you have a soldering gun or corded drill. You could try running it and placing the bar next to it to degauss it. I believe any AC field or motor should work.

You can buy them or make them but a demagnetizer will do the job. My father repaired clocks and watches back in the 80's and he used a L&R brand, I picked one up used on fleebay for around $25 shipped if you catch one at the right time. https://www.ebay.com/itm/Watchmakers-L-R-Demagnetizer-for-the-Watchmaker-Jeweler/392325130414?hash=item5b586668ae:g:C3QAAOSwKYFdGfSA&LH_ItemCondition=4 or for something the size of a bar you could use one like machinist use https://www.ebay.com/itm/DEMAGNETIZER-TOOLS-SUCH-AS-DIES-CUTTERS-AND-PUNCHES-NEW/283552137712?hash=item42050641f0:g:CdEAAOxye5BRETE~

You can also make one yourself out of an old motor, shade pole motor's work great and I have made them in the past doing this https://www.youtube.com/watch?v=8kKTJQTyX-w&t=661s Just remember not to use it to long or it will over heat and burn up the coils, you can also use them to magnetize things as well.

Wrap leads from an AC welder around the bar, and weld a bit.
