MAGNETIC
WAVES uses the magnetic field created by two large coils of copper.
When electricity runs through coils, an oscillating current (AC)
induces a quickly fluctuating magnetic field. The fine magnetic
powder in the dish responds beautifully to this magnetic flux. Tracing
the invisible magnetic currents, long rolling waves of magnetic
powder arch and blossom as visitors create a near-infinite number
of emerging patterns.
