flux freezing

(magnetic field lines becoming attached to plasma they pass through)

Flux freezing is a phenomenon regarding magnetic fields within plasma: if the resistivity is low, the field lines stay with the plasma they pass through even if the plasma is moving, i.e., the more dense and less dense portions of the magnetic field move with the plasma. Neutron stars are presumed to be superconducting, i.e., no resistivity, and the magnetic fields present when they form are frozen in place.
