Pocket Magnetizer/Demagnetizer

[IMR4198]

   Just ran across this small item as I was looking for something else on the Walmart site.  Claims to magnetize or demagnetize tools.  Powerful ceramic magnets.  I don't know anything about it.  A $3 item.  Has a key ring and a bottle opener.  Might have to be careful what you kept this thing around.  Best wishes.  G

Every time I think about demagnetizing, I think of destroying data on diskettes or hard drives.  (My IT mind at work apparently.)  Don't ever consider demagnetizing tools but I do run into times when I don't need/want something magnetized.

I wonder in what application would you need a keychain doohickey version by your side at all times though.

  Think of how easy it would be to tie the doohickie to a stick and use it to reach under the sofa for a lost something or other.  Or maybe reach into a toilet bowl tied to a string if a screw went kerplunk.  Using the cute little key-ring of course.  I saw a u toob video where someone used the magnetizer to make a screwdriver hold little mini phillips screws for hobby work, then demagnetize it afterward to return it to something that didn't stick to everything.  I think I will see if Walmart has them on the shelf?  Could be fun to play with for $3.  Best wishes.  G

Maybe not to EDC, but nice to have in a tool box/case. You could magnetize bits and screwdrivers to keep them from falling/dropping screws and then demagnetize them afterwards to stored them away.

You could magnetize a piece of wire/paperclip around a cane/pole/rope to retrieve something metallic.
