Magnetic reconnection occurs due to flux-breaking behaviour (e.g. finite resistivity) in a medium. But can reconnection be observed in a vacuum (where there may be virtual particles)? Has this been observed?

  • $\begingroup$ If you allow reconnection to include any change in field topology, then the answer is yes. This cannot be observed because there is no where that is a vacuum. The closest thing to a vacuum are the magnetospheres of magnetized planets but even those have a finite number of particles. $\endgroup$ – honeste_vivere Aug 21 '18 at 2:09
  • $\begingroup$ @honeste_vivere "If you allow reconnection to include any change in field topology, then the answer is yes." - How can topology be broken if there is no mechanism to break flux conservation in a vacuum? Or is there an available mechanism? $\endgroup$ – Mathews24 Aug 21 '18 at 13:14
