What causes the neutron to have a magnetic moment , and is it paramagnetic or diamagnetic.

Already in the "naive" constituent quark model, relativistic corrections spoil this simple picture. Note that this "naive" model predicts rather well the ratio of the magnetic moments. But for absolute values, the relativistic corrections from this model do not agree with observations. This is not a simple story, and how the different contributions from quarks spin, gluons spin, and orbital angular momentum add up still under investigation.SpectraCat said:Perhaps it is just that there are always two identical quarks in either of these particles (neutron = 1 "up" and two "down" quarks, while a proton = 2 "up" and 1 "down"), then those two just pair their spins in the anti-symmetric "singlet" state according to the Pauli exclusion principle, and the spin of the remaining quark gives the overall spin of the particle.
ansgar said:the neutron consists of electrically charged particles, quarks, and it has a finite "size" (or rahter a density distrubition)
only materials are paramagnetic, diamagnetic and so on...
cragar said:by materials you mean stuff with atoms , so neutrons are neither paramagnetic or diamagnetic.
The neutron magnetic moment is a measure of the strength of the magnetic field associated with a neutron.
The neutron magnetic moment is paramagnetic, meaning it is attracted to an external magnetic field.
Paramagnetic materials have unpaired electrons, which align with an external magnetic field, while diamagnetic materials have all paired electrons, which are slightly repelled by an external magnetic field.
The neutron magnetic moment is influenced by the spin and magnetic moment of its constituent particles, such as quarks and gluons.
The neutron magnetic moment is important in understanding the structure and properties of matter, as well as in applications such as nuclear magnetic resonance imaging (MRI).
