Awaiting Telemetry

The visual vector field calculates the net electric field at hundreds of points simultaneously across the 2D plane. Use the 3D control arrows on each charge to drag them in any direction (X, Y, Z).

Governing Dynamics

Coulomb's Law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

\vec{F} = k_e \frac{q_1 q_2}{r^2} \hat{r}

The total electric field $\vec{E}$ at any point is the vector sum of the individual electric fields created by each charge in the system (Superposition Principle).
