nuclear magneton
E590881
The nuclear magneton is a physical constant that serves as the natural unit of magnetic moment for protons and other nucleons, analogous to the Bohr magneton for electrons but smaller due to the nucleons’ larger mass.

How this entity was disambiguated
This entity first appeared as the object of triple T6396920 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A.
Bohr magneton
The Bohr magneton is a fundamental physical constant that represents the natural unit of the electron’s magnetic moment in atomic physics.
-
B.
Pauli paramagnetism
Pauli paramagnetism is the weak, temperature-independent magnetic response of conduction electrons in a metal arising from their spin alignment described by Fermi–Dirac statistics.
-
C.
Curie constant
The Curie constant is a material-specific proportionality factor that characterizes how a paramagnetic substance’s magnetic susceptibility varies inversely with temperature.
-
D.
Fermi (unit)
The fermi is a unit of length equal to one femtometer (10⁻¹⁵ meter), commonly used in nuclear and particle physics to express sizes of atomic nuclei and subatomic particles.
-
E.
reduced Planck constant
The reduced Planck constant (ħ) is a fundamental physical constant that quantifies the scale of quantum effects, commonly appearing in formulations of quantum mechanics and quantum field theory.
- F. None of above. chosen

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: nuclear magneton Description of subject: The nuclear magneton is a physical constant that serves as the natural unit of magnetic moment for protons and other nucleons, analogous to the Bohr magneton for electrons but smaller due to the nucleons’ larger mass.
