How do store security devices work?

BlockbusterPseudoTheftFilter: OK, not really stealing, just curious. I rented a DVD from Blockbuster the other day only to find (on returning home) that the clerk had not removed the yellow security tab. On calling the store, I was given the go-ahead to cut the box apart so I could watch the movie without making the trek back. It was easy enough to cut it open from the other side, but it's made me really curious about that security tab, which I thought would come apart much more easily. Which brings me to the question, which has been brewing in the back of my head forever ... does anyone know how these things work, exactly? The best I've been able to discern so far is that magnets are involved.
