Simuladors per visualitzar diferents temes d'electroestàtica

Per visualitzar una mica de tot:

Electrostatics Simulation

http://www.falstad.com/emstatic/EMStatic.html

Per exemple un pot seleccionar “Dielectric Cylinder in Field” i visualitzar la “Polaritzation Charge”, i així amb diverses situacions. No crec que sigui molt útil però pot resoldre algun dubte així conceptual.

Problemes de escorces esfèriques, gràfiques de E(r) i V(r)

Physics Simulation: Electrostatics Two-Shell Analysis

Investigate the electric field intensity and the electric potential in the space surrounding and on the surfaces of two charged, concentric, electric shells.
