magnetized tools
themadhippy:
Give them a short sharp shock,bang the screwdriver against the work bench or lump of metal a few times.
AKM:
You can use a magnet. Rub against either pole to magnetize, rub against the side where you have both poles to demagnetize.
Here is a picture of a magnetizer/demagnetizer to easily demonstrate.
GreyWoolfe:
Just out of curiosity, why do you want to demagnetize? I buy magnetized kits and if I have stuff not magnetized already like my Xcelite 99 series, I magnetize them. I even keep a magnetizer/demagnetizer in my tool bag in case anything gets weak. Never have had an issue in 20 years of field service repairs.

Best thing in the world is one of the old Weller transformer-type soldering guns, the ones with the two-pronged copper tip that is bolted into two
threaded posts that stick out the front of the gun. You squeeze the trigger and then pass the tool through the loop of the tip, pull back out
and then hold far away from the gun when you release the trigger. This totally demagnetizes the tool.

It depends on the job. For some tasks a magnetic tool is good and for others it is causing problems. With a magnetic screw driver the screw on the heat tends to hit the side of a magnetic material. It is especially trouble with a magnetic washer. Magnetized tweezers can be troublesome with small parts - here stainless steel is a common solution, as the magnetic version does not make much sense.
The cases are rare but sometimes one wants it non magnetic.
