PHYIC CALCULATOR
Electric Dipole Field Calculator
A precise tool.
What is the Electric Dipole Field Calculator & How does it work?
An electric dipole consists of two equal and opposite charges separated by a small distance. The electric field at a point along the axis of the dipole can be calculated using the formula:
E = frac{1}{4piepsilon_0} cdot frac{2p}{r^3}
E = Electric field strength, p = Dipole moment, r = Distance from the center of the dipole to the point along the axis.
This formula is valid for points on the axis of the dipole where r is much larger than the separation distance between the charges.

Frequently Asked Questions
How do I calculate the electric field strength of an electric dipole?
Use the formula E = (1/4ΟΞ΅β) * (2p/rΒ³), where p is the dipole moment and r is the distance from the center of the dipole to the point along the axis.
What does the dipole moment represent in this calculation?
The dipole moment represents the product of the magnitude of one charge and the separation distance between the two charges.
When is this formula applicable?
This formula is applicable for points on the axis of the dipole where the distance r from the center of the dipole to the point is much larger than the separation distance between the charges.
What units should I use for the electric field strength?
The electric field strength is typically measured in volts per meter (V/m).
Can this calculator be used for any orientation of the dipole?
No, this formula specifically applies to points along the axis of the dipole. For other orientations, a different formula would be needed.
What is the significance of Ξ΅β in the formula?
Ξ΅β represents the permittivity of free space, a fundamental constant in electromagnetism.
How does the electric field strength change with distance from the dipole?
The electric field strength decreases with the cube of the distance (rΒ³) from the center of the dipole along its axis.
