NOTE: You must be connected to the Internet the first time you view this simulation, at which point the codebase for all the simulations will be downloaded to your computer. This process make take a few minutes, as the codebase is roughly 9MB in size. Subsequent viewings of the applets will run from your local copy.

 
DESCRIPTION:

This java simulation illustrates how it is possible to charge a conductor without having direct contact.

We charge by induction by first bringing the conductor to the proximity of a charged object. If the object's charge is large enough, the charges within the conductor will be separated. Next, we ground the conductor, which allows charges of the same sign as the object to flow away. Finally, we unground the conductor, and discard the object. The conductor is now charged, and has the opposite sign of the original object.
