Solar Dancer

Share n' Tell, NCNAAPT Fall Meeting, City College of San Francisco - November 15th, 2014

I found this Solar Dancer at the local Dollar Tree. It has a photocell (light sensitive panel) that collects light and causes the dancer to move side to side. The photocell sends current through the coil which creates a magnetic field. The magnetic field from the coil interferes with the permanent magnet's magnetic field and causes the small figure to move.
