Concept
Electric dipole field
Exam focus
Remember that the axial field magnitude is twice the equatorial magnitude at the same distance, and both scale as 1/r³ in the point-dipole limit.
Common mistakes
- Do not use the axial formula for an equatorial point.
- Keep the dipole moment in C·m and distance in metres.
- Track field direction separately from the magnitude.
How to verify your answer
Check the 1/r³ scaling and confirm that the point-dipole approximation is valid.
Model limits
This result is valid only under the assumptions stated on the calculator page. For real systems with non-ideal geometry, losses, distributed effects or relativistic/quantum corrections, use the appropriate advanced model.
