What the Expert Says:

Yes, for a given magnetic material, the greater its volume, the more atoms it has and the more atoms adding their fields together, the stronger the field. If we interpret strength as lifting force, the larger magnet, having a greater flux, is stronger. Of course you can put identical small magnets side-by-side and end up with the same field strength but a larger lift force. You can state an hypothesis as: "If the same magnetic material has a larger volume, it will then be able to lift a larger metallic weight."
