De-magnetizing tools

[NOBLNG]

I have a pair of tweezers that have become horribly magnetic. I dragged them through this thing a number of times and couldn’t get rid of the magnetism. There are units that are 115v powered...but I have this. Eventually, I re-magnetized them first, then de-magnetized them and it worked....but only for a little while.?? Does anyone have another way or do I need a powered one?

I always had that problem too. None of the so-called demagnetizers (like the green one you have) worked for me. I finally bought (on eBay) an old Akai bulk magnetic (reel-to-reel) tape eraser.  It is a Degauser (basically a hefty iron-core coil powered by the 120V AC) The AC part is what does the work (it flips the magnetic field 60 times per second).  I no longer have any magnetic tools when I don't want them to be magnetized.  And they stay that way!  That thing is so powerful that i can put a dozen of small steel tools into a plastic tray, and pass them through the magnetic field to be demagnetized all at one. Problem solved!

Well how about that!? Running it once in and out of the center of my soldering gun worked...and the thing was sitting in a drawer right beside me all the time. Thanks for the link Bill.?
