I use magnets that are stronger in gaming figures. I have a board game that came with a bunch of "Armor Kits" for the plastic figures. If I just used plastic cement to assemble them, they would no longer be customizable. Instead I drill out small holes for magnets on the various pieces, superglue them in there, and then I can swap our pieces as needed. I suppose the end goal is still entertainment, but they are a utility piece in this example, and you could use them similarly for anything you are building where you want a small magnet.
