Electric Field: What is Wrong? Package
written by Anne Cox, Wolfgang Christian, and Francisco Esquembre
The EJS Electric Field: What is Wrong? Package is a collection of models for electrostatics with errors intentionally built into each model.  Users can move charges around and see the force, observe the electric field generated by charge configurations, and observe the motion of test particles in electric fields to try to identify the errors in the simulation. Users can inspect, modify and correct any simulation in the package by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item. The package also includes a brief overview of programming basics needed to correct the models.

The Electric Field: What is Wrong? Package was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_em_electric_wiw.jar file will launch the package if Java is installed.  Navigate within the package and click on a green triangle to run a particular simulation. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.  Additional Ejs models are available on ComPADRE.

Please note that this resource requires at least version 1.5 of Java (JRE).

4. THE PHYSICAL SETTING

G. Forces of Nature
  • 4G (9-12) #3.  There are two kinds of charges?positive and negative. Like charges repel one another, opposite charges attract. In materials, there are almost exactly equal proportions of positive and negative charges, making the materials as a whole electrically neutral. Negative charges, being associated with electrons, are far more mobile in materials than positive charges are. A very small excess or deficit of negative charges in a material produces noticeable electric forces.

Electric Field: What is Wrong? Package:

Covers the Same Topic As Coulomb's Law and Electric Field Package

Coulomb's Law and Electric Field package shows correct versions of similar simulations.

relation by Anne Cox
Is Based On Easy Java Simulations Modeling and Authoring Tool

The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the Electric Field: What is Wrong? Package.
