In this simulator you can explore the behavior of the Faraday Pail. An option to color charged surfaces red and blue provides a model view of the process. Below, a red charged insulator is lowered into the uncharged Faraday Pail. The changing thickness of both the inside blue coloring and outside red coloring of the Pail suggest the polarization that is occurring.
Below, a hand "grounds" the Pail. When the red-charged insulator is removed, the Faraday Pail becomes blue-charged. On the right is a snapshot of a ultrascope tool that provides a simple microscopic model of the charge distribution on any surface.
A Graphics palette includes tools that enables you to annotate and draw on the simulator, and to take snapshots.
