a neutron vortex line's strong magnetic field
http://www.ias.ac.in/jarch/jaa/16/207-216.pdf
In this paper is mentioned "a neutron vortex line's strong magnetic field." The neutron vortex must be the vortexes that form in a rotating superfluid, and the line is the axis of rotation of this vortext. But how do they produce a magnetic field? I don't know much about electromagnetism. I thought that magnetic fields were produced by a charge moving in a magnetic field. Neutrons have no charge. So... how does this work? |

I don't know much about electromagnetism. I thought that magnetic fields were produced by a charge moving in a magnetic field. Neutrons have no charge. So... how does this work? Neutrons do actually have charges that cancel each other out over large distances but are measurable over very small distances (within few multiples of the neutron radius). Think about what a neutron is made up of: three quarks, two down quarks and one up quark. The down quarks each have a charge of -1/3 of an electron, while the up quark has a +2/3 of an electron. The two down quarks make up 2 out of 3 corners of the neutron, while the up quark makes up the the third corner. So two corners are negatively charged, while one corner is positively charged. So the neutron will differential feel charges at short distances, which will cause the neutron to start spinning due to a magnetic torque.

No, magentic fields are produced by moving charges. *Neutrons have no charge. So... how does this work? Since you didn't do any research since my last answer, I suspect this will go over your head too. The thing that keeps a neutron star from collpasing into a black hole is "neutron degeneracy pressure". This is neutrons decaying back to protons and electrons, however briefly. There is charge. What is more, the surface of a neutron star is normal matter... iron and such. That will present the necessary resistance to permit some separation of charges. David A. Smith |

He's talking about just neutrons by themselves, like inside atoms, not neutron stars. No he's not, he's referencing a paper on neutrons stars. That he did not bother to do any research since he asked about neutron degeneracy pressure, he may not be aware that neutron stars are not just neutrons. But maybe bringing it home a bit more will help. David A. Smith |
