Charge Trajectories in 3D Electrostatic Fields Model

written by Andrew Duffy

The Charge Trajectories in 3D Electrostatic Fields model investigates a charged particle, and the forces exerted on that charged particle by electric and/or magnetic fields. First, see how the charge behaves when exposed to just an electric field. Then, see how the charge behaves when exposed to just a magnetic field. Finally, if you'd like, turn both fields on and see what happens.

The Charge Trajectories in 3D Electrostatic Fields model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_bu_duffy_Charge_Trajectories_in_3D_Electrostatic_Fields.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).

bug fixed here Ejs Open Source Motion of Charge Particle in Electric & Magnetic Field in 3D

Author: lookang
Posted: October 27, 2010 at 1:56AM

vx = vxinit; // added by lookang to initialize page
vy = vyinit;
vz = vzinit;
the sliders vxinit, vyinit and vzinit need to add _initialize() to the action on drag.

i have remix a version of this applet here
