I don't think magnets wear off over time unless they're either incredibly cheap or if they accumulate a lot of oils and grease on them. I've never had a magnet fail on me before unless it's been those really crappy tiny one's.
And you can get very good small ones. A lot of my premium OC Steel books have very strong magnets on the flaps. I've not worry for them.
