This is a step-by-step Java simulation on electrostatic induction, showing how it is possible to charge a conductor without direct contact. A conductor is placed in close proximity to a charged object (the user controls amount of charge from -200 to 200.) The applet then simulates the process of charge separation within the conductor. Click on "Ground" and watch charges of the same sign flow away. Then click on "Unground" to see that the conductor is now charged, and has the opposite sign of the original object.

EDITOR'S NOTE: This simulation offers students a particularly rich experience. At any time, they may view the changing electric field as a "grass seeds" representation or as electric potential lines. Clicking and dragging anywhere within the field will allow a 3-D view of the system.

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.

Topic: "Static" Electricity
Unit Title: Electrostatic Induction

This Java simulation from MIT is one of our top choices to model the process of electrostatic induction. It breaks the process down into steps: charge separation within the conductor, grounding of charge, and ungrounding. It gives students an especially rich experience, as they can observe the changing electric field as "grass seeds", electric potential lines, or in a 3D view.
