Electromagnetic fields around neutrons?

Click For Summary

Discussion Overview

The discussion centers on the electromagnetic fields associated with neutrons, specifically exploring the existence and properties of electric and magnetic fields around them. Participants inquire about the field strength distribution and any research conducted on these topics, touching on theoretical aspects of particle physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that neutrons, composed of three charged quarks with a net charge of zero, should have an electric field surrounding them due to the spatial constraints of the quarks.
  • Others assert that a neutron has a magnetic field as a particle with spin 1/2, despite having no net electrical charge and a limited charge form factor.
  • One participant questions the magnitude and distribution of the electric and magnetic fields around neutrons and seeks existing research on these properties.
  • Another participant claims that because the quarks in a neutron are predominantly in a state of zero angular momentum, there is no electric field outside the neutron, although there is an electric field within a radius of about 1 fm, and the magnetic field outside behaves like that of a magnetic dipole.

Areas of Agreement / Disagreement

Participants express differing views on the existence and characteristics of electric and magnetic fields around neutrons, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Some claims depend on specific assumptions about the states of quarks and the nature of electromagnetic fields in neutral particles, which are not fully explored or agreed upon in the discussion.

The nuetron has a known substructure of three charged quarks with net charge 0. Still, these quarks cannot occupy the same space simultaneously, so neutrons should have an electric field surrounding them.

Has any work been done to find the properties of this field? For example, what is the electric field field strength distribution around the newtron? Does it have a magnetic field around it? If so, what is its field strenght distribution?

(Note that I realize the magnetic field strength is relative to the motion of the observer.)

Corrected slips of the pen.

Are you asking about neutrons or neutrinos? Obviously about neutrons.

Yes, a neutron has a magnetic field as a particle with a spin 1/2. No net electrical charge and rather limited charge formfactor.

You know, another electrically neutral system - positronium, is in somewhat similar situation.

What about the magnitudes of the fields and the magnitude distribution? Have there been done any research on them?
 
Because the quarks in a neutron are predominantly in a state of zero angular momentum, there is no electric field outside the neutron. There is an electric field inside the neutron's radius of about 1 fm. The magnetic field outside a neutron is that of a magnetic dipole.
