Neutron magnetic moment.html



The neutron magnetic moment is the magnetic moment of neutron. It was of particular interest, as magnetics moments are created by the movement of electric charges. Since the neutron is a neutral particle, the magnetic moment is an indication of substructure, that the neutron is made of other, electrically charged particles (quarks).

Value

The neutron magnetic moment of neutrons is measured to be −1.9130427(5) μ_N, where μ_N is the nuclear magneton.¹

In SI units, the neutron magnetic moment is approximately −9.6623640 × 10⁻²⁷ J/T

Physical significance

The magnetic moment is negative which means that the neutron has a tendency to align antiparallel to a magnetic field rather than parallel to the field.

The non-zero magnetic moment of the neutron indicates that it is not an elementary particle, as it carries no net charge but still interacts with a magnetic field.
