Can a magnet exert a force on a grape? Find out with this Exploratorium activity. You'll see how to mount two grapes on a straw, so the tiny diamagnetic force produces observable motion. The site also contains an explanation of the physics involved and descriptions of ferromagnetic and paramagnetic materials.
