surprisingly simple exhibit, MAGNETIC SPINNER uses the scrapings
from videotape and six rotating ceramic magnets to produce beautifully
complex spiral patterns. Visitors spin the magnets using a hand
held disc that can be freely maneuvered below the magnetic powder.
The powders delicate response allows visitors to see the intricate
interactions of the rotating magnetic fields. The mesmerizing effect
is highlighted with a viewing lens and a low heat halogen light.
