The electric field of a dipole is a source-free, irrotational vector field with both zero divergence and zero curl. This unique combination means the field can be described by both a scalar potential (electric potential) due to its irrotational nature and a vector potential due to its source-free nature, and that the work done by the field is path-independent.

The force field from an electric dipole has a divergence of zero ( $\nabla \cdot F=0$ ) for all points not at the origin. This means the field is source-free, as it originates from charges but does not have a net "source" or "sink" at any point in space. This is a defining characteristic of a solenoidal vector field.
The force field also has a curl of zero ( $\nabla \times F=0$ ). This indicates that the field is conservative or irrotational, meaning that the work done by the force in moving a charge between two points is independent of the path taken.
