Point Charge Electric Field JS Model
written by
Wolfgang Christian and Anne Cox
This page features a set of three models for exploring electric field strength and direction using one or more point charges. Positive point charges are represented as red circles; negative point charges are blue circles. The simulations display the electric field using color-coded unit vectors together with a draggable "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. Editor's Note: Teachers: A test charge is a representation, given a specific charge quantity denoted by the symbol "q". When placed in the electric field, the test charge will experience attraction to or repulsion from the positive or negative "point charges". Test charges are used to test the strength of an electric field.

This resource is part of a Physics Front Topical Unit.
Topic: "Static" Electricity
Unit Title: Electric Field This set of three models would be a great choice for an inquiry-based exploration of electric field strength, attraction/repulsion between positive and negative charges, and factors that affect the direction of field lines. We recommend allowing one class period for students to explore the models before introducing labs on electrostatics. Each model includes accompanying problem sets. Link to Unit:
