Levitation By Magnetism
The four magnets in this set can be made to float in mid air when in one certain configuration. Use your knowledge of magnetism and your scientific skills to arrange the magnets on a thin sheet of sheet metal so that alternating poles create a strong magnetic field gradient.
This gradient centers the pyrolytic graphite material of the magnets for levitation. Pyrolytic graphite is 10,000X more diamagnetic than most common diamagnetic materials like water, and these thin slices are extremely light and can be made to levitate.
Kit includes four neodymium magnets, one steel base plate (1"x 1" x .036" thick), a plastic dome, and pyrolytic graphite.
