Q. A rectangular bar magnet is broken in half longways. The resulting pieces are: Answer: as magnetic as the original magnet. I don't see why it isn't half as magnetic. I broke one of my fridge magnets in half, and I'm tellling you, it's only half as strong now. It can't hold the recipe up on the door anymore. My professor says my experiment is invalid, but won't say why. Is it really as "magnetic" as the original magnet? It sure seems only half as strong. Thanks for any insight.
