Point Charge Electric Field JS Model
written by Wolfgang Christian and Anne Cox
The Point Charge Electric Field JavaScript model shows the electric field from one or more point charges. The simulation displays the electric field using color-coded unit vectors together with a draggable an test charge and its force vector. The field magnitude is shown in a yellow message box near the bottom of the view as the test charge is dragged.

The Coulomb's Law and Electric Field JavaScript model was developed using version 5 of the Easy Java Simulations (EJS 5) modeling tool. Although EJS is a Java program, EJS 5 creates stand-alone JavaScript programs that run in almost any browser.

AAAS Benchmark Alignments (2008 Version)

11. Common Themes

11B. Models
  • 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.

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.
