Editing Magnetar (section)

====Origins of magnetic fields====
The dominant model of the strong fields of magnetars is that it results from a [[magnetohydrodynamic dynamo]] process in the turbulent, extremely dense conducting fluid that exists before the neutron star settles into its equilibrium configuration.<ref>{{Cite journal |last1=Thompson |first1=Christopher |last2=Duncan |first2=Robert C. |date=1993 |title=Neutron Star Dynamos and the Origins of Pulsar Magnetism |url=https://articles.adsabs.harvard.edu/pdf/1993ApJ...408..194T |journal=Astrophysical Journal |volume=408 |pages=194–217 |doi=10.1086/172580 |bibcode=1993ApJ...408..194T |via=NASA Astrophysics Data System |doi-access= }}</ref> These fields then persist due to persistent currents in a proton-superconductor phase of matter that exists at an intermediate depth within the neutron star (where neutrons predominate by mass). A similar magnetohydrodynamic dynamo process produces even more intense transient fields during [[Neutron star merger|coalescence of a pair of neutron stars]].<ref>{{Cite journal
