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.

This applet simulates the magnetic field of a long current-carrying wire and a compass needle, along with the dynamics of their interaction.
