This item is an interactive Java simulation that illustrates the structure of two-dimensional vector fields using the "grass seeds" (or "iron filings") representation. Users enter x and y components for a field, then choose from a variety of field examples: two-point charges, dipole in constant or no field, two-line currents, radiating dipole, and dipole in a field with gradient. The applet will display the chosen field in either a grass seeds electric field or as equipotential lines. For more advanced users, the applet provides functions for yielding polar coordinates.

This item is part of a collection of visualizations developed by the MIT TEAL project to supplement an introductory course in calculus-based electricity and magnetism.
Lecture notes, labs, and presentations are also available as part of MIT's Open Courseware Repository:

MIT Phyics 8.02: Vector Fields - Mapping Fields Applet:

Covers the Same Topic As MIT Physics 8.02: Electrostatics - Two Point Charges

This Java applet is a much simpler version of the same topic, in which learners move two opposite point charges around to see the resultant field. Magnitude of charge can be changed by the user.
