Does anyone know a better way to demagnetize (yes, DEmagnetize) the security strips in books, and thereby reactivate them? It's such a massive waste of time, the way we do it now! One book at a time, THUNK!, THUNK!, THUNK! There must be a better way. I've tried to conduct whatever magnetic field is generated by the thunker with wire and a slinky, with no success. I honestly don't see how you can demagnetize something in the first place, so I'm about outta ideas. Anyone have any experience in this area? Any clues?

Unfortunately, almost all the Libraries that I've seen have demagnetizers that disable the security strip one book at a time. I have a feeling that this is something that you might have to get used to.
Other than that, how is the job?

No.
More powerful magnets may damage other equipment.
We don't have them here, though. Our security system consists of eagle-eyed ladies and one (1) rabid Children's Librarian.

Bear in mind that Omega is not talking about disabling the security strips. He's talking about activating them before they go back on the shelf: setting them to make the alarm go off. And, yes, that consists of demagnetizing them. It seems backward, but it's true.

Isn't a matter of when it's magnetised, all the atoms/charges point in the same direction, and when it is de-magnetised, the atoms/charges are scrambled?

My school's main library lack even such a system, they must bag check everyone as they leave. This is an university we're talking about, too.
