Formula and methodology
Formula: p = qd; Eaxial = 2kp/r³; Eequatorial = kp/r³; Vaxial = kp/r² and Vequatorial = 0 in the far-field idealization.
The calculator uses the point-dipole approximation, where two equal and opposite charges are represented by their separation and dipole moment. Axial and equatorial observations have different field factors.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Magnitude of either charge — C; minimum 1.0E-12; maximum 1000000
- Charge separation — m; minimum 1.0E-6; maximum 1000000
- Observation distance — m; minimum 1.0E-6; maximum 1000000
- Observation line — 2 choices
Worked example
| Input | Value |
|---|---|
| Magnitude of either charge | 1.0E-6 |
| Charge separation | 0.02 |
| Observation distance | 1 |
| Observation line | axial |
The dipole moment is 2.0×10⁻⁸ C·m and the axial field is about 359.5 N/C.
Assumptions and limits
- The observation distance is large compared with the charge separation so the ideal point-dipole approximation is appropriate.
- The result is a magnitude; charge orientation and field direction are not returned.
- The medium is vacuum and local conductors, polarization, and higher multipole terms are excluded.
