Brief instructions:

• Create two Elements (circles)
  PROCEDURE: Press the right mouse button on the 'table' to display the main dialog. Select Element/Create Circle  from the dialog, choose the position and confirm by pressing the left button once. Finally, set the radius of the circle by dragging the mouse.
  
• Charge the Elements
  PROCEDURE: Select Particle/Creatie Positive from the dialog. Move the mouse pointer above the element (the border of the element changes color) and use the left mouse button to add  particles to the selected element.
  
• Move an element and observe the forces (Vectors)
  PROCEDURE: Select Element/Move and drag the element around.

Translate menu:

Change the names in the file .. jacob\data\ui.dat

Enable gedgeds and detectors: potential, electric force strength, energy, capacitance, current, and many more

Example: With commands  Scene, Show Gadgets, Add, Energy Gauge, put the gadged on the screen and than enable it applaing klick on small button at left upper corner of the gadged and than press the left button and move the pointer on the workbench in case of detector  or just click the object in case of gauge. We can on-line detect the values of phisical quantities under consideration.

How to create own experiment?

Set-up elements using graphic editor:
Place positive/negative charged particles within elemets border by clicking wit left button :
Save the experiment set-up "name.jco" in to folder jacob/jco:
Adjust the experiment parameter using menues Modifiers, Forces or edit the file "name.jco"  with text editor.
