Rated 2 out of 5 by from Use carefully! I used these magnets to separate iron from breakfast cereal and it worked great, however, the magnets chip very easily. I'm not comfortable with the idea of small pieces of a powerful magnet being left behind or scattered in the classroom. Perhaps they should be wrapped in something to prevent this from happening?
