Electric fields

  When you move then mouse on the screen, the program shows a vector that indicate, at every point, the electric field created by:


  On the tool bar it is possible to choose the field.

  By clicking, the vector remains on the screen.

  By clicking button   ,   in the case of several charges, the program draws also the vectors that represent the fields created by any charge.

  By clicking button     the program erases the vectors drawn on the screen.

  By clicking button     the program draws the lines of force.

  By clicking button     you can charge another language.

  Button     opens this help windows.

  On the status bar, the following values are shown in arbitrary units of measure:

  • intensity of the electric field E,
  • intensity of the electric field E of the components (case of more charges),
  • potential V,
  • distance r (case of point charge).
