This is a simulation about an electric dipole.
It’s possible to move the two charges q
1 and q2 generating the field and the point P in which the electric field is measured (click the mouse on them and drag).
In the point P are also shown the electric field vectors generated by q1 and q2, their vectorial sum (that is the total electric field vector in P) and the field line passing through it (red line).
With the two q
1 and q2 sliders (in the field parameters tab) it’s also possible to change the charge intensities of q
1 and q2 and see how the field lines change (especially comparing their configuration when the charges have opposite sign values or when they are equally signed).
