Strange question for the group. I used my favorite pliers to make
some magnetic clasp/chain extenders and now the pliers are
magnetized. How on earth do I de-magnetize them. They are very
irritating when allthey do is stick to other pliers.
See if you can find an old-school TV repair shop. They have a tool
called a degaussing coil. They were commonly needed for the old CRT
monitors, but many older shops still have one tucked away in the
back. Some machine shops have a similar tool to degauss tool bits.
An alternate, but less reliable, method is several light strikes
with a hammer (not enough to mark or deform the tool) to "reset" the
grain structure, or to heat the tool to the non-magnetic temperature.
