The CODATA recommended value for the magnetic moment of the proton is μ p = 2.792 847 344 63 (82) μ N ‍ = 0.001 521 032 202 30 (45) μ B. ‍ The best available measurement for the value of the magnetic moment of the neutron is μ n = −1.913 042 76 (45) μ N. ‍ Here, μ N is the nuclear magneton, a standard unit for the magnetic moments of nuclear components, and μ B is the Bohr magneton, both being physical constants. In SI units, these values are μ p = 1.410 606 795 45 (60) × 10 J⋅T ‍ and μ n = −9.662 3653 (23) × 10 J⋅T. ‍ A magnetic moment is a vector quantity, and the direction of the nucleon's magnetic moment is determined by its spin. The torque on the neutron that results from an external magnetic field is towards aligning the neutron's spin vector opposite to the magnetic field vector.
