The Point Charge Electric Field Demo model shows the electric field with multiple point charge configurations and vector field visualizations. Users can select these configurations from a drop down menu or can create their own configurations.
The Point Charge Electric Field Demo model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double click the ejs_em_PointChargeElectricFieldDemo.jar file to run the program if Java is installed.

The Single Charge Electric Field model shows the electric field from a single charge and introduces the concept of a vector field. The electric field is defined as the force per unit charge that would be experienced by a very small test charge at a given location. The Single Charge Electric Field model shows an ideal test charge with an arrow that represents the field at the test charge location. The field magnitude is the length of the arrow at the test charge location and its value is shown in a textbox near the bottom of the view as the test charge is dragged.
