The Electrostatic Zoo simulates the interaction
between charged particles, and illustrates the electric
fields generated as a result. Charges in the Zoo interact
via the Coulomb force, with a Pauli repulsive force
at close distances and a damping force proportional
to velocity. The fields can be visualized in two ways:
a "grass-seeds" representation (click on "Grass
Seeds "), or a traditional vector field representation
(adjust the "Field Visualization" slider),
in addition to the real time renderings of the local
field around each particle.
Use Start button to start simulation. Use Pause button
to pause simulation. Click and drag on any particle
to change its position. Use "Grass Seeds"
to get a "grass-seeds" representaton of the
electric field. Use "Equipotential Lines"
to get a representaton of the electric potential field.
Select and click "remove" to remove charge.
Use "Add Random Positive" and "Add Random
Negative" to add a positive or negative charge,
respectively. Use "Toggle Field Lines on Selected"
to toggle fieldlines on the selected charge(s). Control-click
to select multiple charges.
