Description:
This Java applet was designed to enhance understanding of electric field lines. By "drawing" lines from simulated charges on a color-coded field, the learner can explore vector field diagrams and form concepts about strength/direction of field lines. Sign and ratio of charge can be changed. This activity is appropriate for introductory and algebra-based physics classes. It is part of a larger collection of NSF-funded physics animations and simulations for use in the interactive classroom.
