Meaning and Definition
The electrostatic force field surrounding an electrically charged particle or object.
The region of space in which a stationary electric charge exerts a force on other charges, described by Coulomb's law. In broader physics contexts, it can refer to the classical electrostatic field component of a more complex electromagnetic field.

Common Mistakes When Using “coulomb field”
- Pronouncing 'coulomb' as /ˈkʌləm/ (like 'column').
- Using it to describe a changing electromagnetic field (it's specifically electrostatic).
- Misspelling as 'coloumb field' or 'coulumb field'.
- Treating it as an uncountable noun (e.g., 'much coulomb field').
FAQ
Frequently Asked Questions
In the context of stationary charges (electrostatics), they are essentially synonymous. However, 'electric field' is a broader term that also encompasses fields from changing magnetic fluxes, while 'coulomb field' specifically implies the static field described by Coulomb's law.
Charles-Augustin de Coulomb (1736–1806) was a French physicist. He formulated Coulomb's law, which quantifies the electrostatic force between two charged particles. The unit of electric charge, the coulomb (C), and the term 'coulomb field' are named after him.
Yes, absolutely. A coulomb field is a fundamental property of a charge and exists in a vacuum. In fact, Coulomb's law is defined for point charges in a vacuum. In materials, the field is modified by the presence of other charges.
You would use it for precision, typically in advanced physics or engineering, to emphasise the static, inverse-square law nature of the field. It's common in phrases like 'coulomb field approximation' or when contrasting with other field types (e.g., 'radiation field').

Coulomb field is usually technical/scientific in register.
Coulomb field: in British English it is pronounced /ˈkuːlɒm fiːld/, and in American English it is pronounced /ˈkuːlɑːm fiːld/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a single, stationary charge sitting in space. The invisible 'force halo' it creates, pushing or pulling other charges, is its COULOMB FIELD. Remember Charles-Augustin de COULOMB, who discovered the law describing this force.
Conceptual Metaphor
A FIELD is often conceptualised as a region of influence (like a farmer's field, but for forces). The COULOMB FIELD is the 'sphere of influence' of an electric charge.
