We used t use those in our school library, and some public libraries also do. They should be as close to the binding as possible, preferable so as to be invisible so people cannot remove them. I'm not sure hwo they're affixed, but when we did it it was by hand, and they're very sticky, so sometimes people didn't get them exactly in the right place. I've seen a couple on books. As you may have guessed, they're a security feature. If you buy the book in the store, or take it from a library that uses that feature, the book isdemagnetized when you check it out. Otherwise it will set off an alarm as you walk through whatever you walk through to get to the door.
