Defying gravity? That’s what these magnets appear to be doing as they climb up a pencil. What happens if you turn the magnets over? What does the magnetic field of a ring magnet look like—can you map it? These magnets will add a new dimension to your magnet studies. Magnets 34 mm in diameter, 9 mm thick with an 8-mm diameter hole. Two magnets per set.
