Demagnetizing tools?

[JobeFabrications]

I have a couple of tools that have become magnetized for some reason and looking for a way to demagnetize them. Anyone have any tips?

I have one of THESE, and it seems to work just fine.

Stroke them on the opposite pole of a strong magnet.

Hit them against something.

Or a combination.

If you have mics, verniers, or some other calibrated tool, DO NOT bang it on something.

The combo magnetizer or demagnetizer shown above can be bought relatively cheap. Through Reid Supply www.reidsupply.com the one like the one above is $5.98. Travers www.travers.com carries them for $5.75 each. Or in Travers catalog, they have an electric demag for $72.09.

If just per chance you would happen to buy an electric demag....if you turn it on and pass it over the top a few times, you don't have to have the part directly on top, just wave it across a few times and pull it off first before shutting the demag off, it will demagnetize your part. BUT, if you lay the part on the demag for a few seconds, shut it off while your part is still laying on it, your part will be magnetized

Does that not go without saying?

Thanks guys. The tools in question are a couple of flat files and my center punch.

Grinding dust stuck to them? It is possible it isn't the tool that is magnetized, but the grinding dust. I beat the piss out of my center punch before someone told me it was the grinding dust that was the problem! When the metal is ground it goes from screaming hot to cold quickly which magnetizes the grinding dust. The only solution I have is to rap the tool against something solid to knock the grinding dust off of it when I need to use it.

I use the coil from an old fan.

You'd be surprised as to how some people treat their tools. If you tell them to tap something to demagnetize it, they wouldn't care if it was a block of steel or calibrated gages.

At work we use a snap growler armature tester to demagnetize parts before
assembly .They bought a brand new unit and cut off all the electrical
probe leads .

FYI never gave much thought about magnets, I have a pretty wicked one in the garage, found out lately, since my implant of a defibrillator and pacemaker, its a good idea not to get too close to a powerfull magnet. No formal proof, just a lot of warnings seen on some equipt I've used

 

[Garage5.9]

you could always use some heat , how much im not sure but i do know heat will kill magnets

Got one of those, not the that make but its just the same.

Works for magnetising screwdrivers and demagnetising whatever fits in through its holes.

basta passar por dentro de um motor se o induzido !pronto !!

HF had those on sale for something like $2.98 a couple of week ago. I'm sure Lowes and such has them or almost any hobby store will carry them.

I think the store security tags run on some kind of magnetism. Roll in there with your tools in a brown paper bag and have them give the bag a few shots from the little scan pad thingy. Im sure no one will think you are a weirdo ,lol.
