magneton
C2Technical/Scientific
Definition
Meaning
A unit of magnetic moment used in atomic and nuclear physics, specifically the Bohr magneton (for electrons) or nuclear magneton (for protons/nuclei).
In physics, a quantized measure of the magnetic moment generated by the orbital motion and spin of a charged elementary particle within an atom.
Linguistics
Semantic Notes
Almost exclusively used in quantum physics, atomic physics, and electromagnetism. Not a term of general English. The plural is 'magnetons'.

Examples
By Part of Speech
noun
British English
- The Bohr magneton is a fundamental constant in atomic physics.
- His research involved precise measurements of the nuclear magneton.
American English
- The magnetic moment of the electron is roughly one Bohr magneton.
- They published a paper on the revised value of the magneton.
Examples
By CEFR Level
- In simple terms, a magneton is the natural unit for measuring magnetism inside an atom.
- The anomalous magnetic moment of the particle deviated from the predicted value of one magneton.
- Calculations showed the magnetic moment to be 2.5 nuclear magnetons.

Memory Aids
Mnemonic
Imagine a tiny 'magnet' for an 'atom' – an ATOMIC MAGNET unit = MAGNETON.
Conceptual Metaphor
QUANTITY IS NUMBER; INTRINSIC PROPERTY IS A MEASURABLE OBJECT.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the similar-sounding Russian word for 'magnet' ('магнит'). 'Magneton' is a specific scientific unit.
Common Mistakes
- Using 'magneton' to refer to a large magnet (it's a unit, not an object).
- Confusing 'Bohr magneton' (electron) with 'nuclear magneton' (proton/nucleus).
- Misspelling as 'magnetron' (a different device for generating microwaves).

FAQ
Frequently Asked Questions
The Bohr magneton (μ_B) is the magnetic moment of an electron due to its orbital or spin motion. The nuclear magneton (μ_N) is the magnetic moment of a proton or nucleus, which is about 1/1836 times smaller because the proton is much heavier.
No, it is a highly specialized term used only in physics. You will not encounter it in everyday conversation, news, or general literature.
Yes, the plural is 'magnetons' (e.g., 'The magnetic moments were 2.3 and 2.5 magnetons').
A common mistake is confusing it with 'magnetron', which is a vacuum tube used to generate microwaves in radar and ovens. They are completely different concepts.
