The lower bags on some dust collectors are a bit loose, which makes them a pain to re-install after emptying. As you attempt to operate the strap clamp that holds them in place, they keep sliding down out of position. If you hold the bag in position with magnets, you’ll have both hands free to tighten the clamp. It works beautifully, and the magnets can stay attached to the dust collector when not in use.
