The set-up area of the simulator consists of four pivot points. On each pivot you can place a temporary electric dipole (insulator or conductor), a permanent electric dipole (electret), a temporary magnetic dipole, or permanent magnetic dipole (magnet). Three types of sources can be placed anywhere in the set-up window: permenent electric monopoles and dipoles, and a permenent magnetic dipole. When the simulator is turned on, all the pivoted dipoles respond to sources.
You can also represent the positive and negative surface charge on the pivoted electric dipoles by turning on a special color function: red for positive, blue for negative. There is also a simple microscopic model view for both the electric and magnetic pivoted dipoles.
The Graphics palette is also available, including the snapshot tools, to enable students to represent their own predictions.
