electrostatic field
C2Technical/Scientific
Definition
Meaning
A region of space around an electrically charged object where other charged objects experience a force.
In physics and engineering, a vector field representing the electric force per unit charge that would be exerted on a positive test charge at any point in space, created by stationary electric charges.
Linguistics
Semantic Notes
Always refers to the field produced by stationary charges (electrostatics), as opposed to changing electric/magnetic fields. Often contrasted with 'magnetic field' or 'electromagnetic field'.

Examples
By Part of Speech
verb
British English
- The charged sphere electrostatically fields the space around it.
- The device is designed to electrostatically field the particles.
American English
- The charged sphere creates an electrostatic field in the surrounding space.
- The apparatus electrostatically fields the area to prevent dust accumulation.
adverb
British English
- The particles interacted electrostatically within the field.
- The device operates electrostatically to separate materials.
American English
- The force acts electrostatically due to the stationary charges.
- The system is shielded electrostatically.
adjective
British English
- The electrostatic field strength is measured in volts per metre.
- We observed an electrostatic field phenomenon in the lab.
American English
- The electrostatic field intensity is crucial for the experiment.
- An electrostatic field mapping was performed.
Examples
By CEFR Level
- A balloon can make your hair stand up because of an electrostatic field.
- An electrostatic field exists around any object with an electric charge.
- Scientists can map the electrostatic field around a complex shape using computer simulations.
- The perturbation of the ambient electrostatic field by the approaching thundercloud was detectable by our instruments.
Learning
Memory Aids
Mnemonic
Think of a balloon rubbed on hair – the invisible 'force halo' that makes your hair stand up is an electrostatic field.
Conceptual Metaphor
An invisible web of force lines emanating from a charged object, like the warmth radiating from a heater.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation of 'field' as 'поле' without the electrostatic context; ensure the full term 'электростатическое поле' is used.
- Do not confuse with 'электромагнитное поле' (electromagnetic field), which is broader.
Common Mistakes
- Using 'electrostatic field' to describe fields from moving charges (those are electromagnetic fields).
- Confusing it with 'electric potential' or 'voltage'.
- Omitting 'electrostatic' when context is unclear, leading to ambiguity with time-varying electric fields.

FAQ
Frequently Asked Questions
In common technical usage, 'electric field' is the broader term. An electrostatic field is specifically the electric field produced by stationary (static) charges.
The standard SI unit is volts per metre (V/m). It can also be expressed in newtons per coulomb (N/C), as it represents force per unit charge.
No, it is invisible. However, its effects can be observed (e.g., attracting small pieces of paper, causing hair to stand up) and it can be mapped using sensors or visualized with field line diagrams.
An electrostatic field is created by and exerts forces on electric charges, regardless of whether they are moving. A magnetic field is created by moving electric charges (currents) and exerts forces only on moving charges.
