Electromagnetic fields around neutrons?

[espen180]

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 realise the magnetic field strength is relative to the motion of the observer.)

EDIT:
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.
