frozen magnetic field line
  خط ِ میدان ِ مغناتیسی ِ یخ‌بسته، ~ ~ ~ رچیده   
xatt-e meydân-e meqnâtisi-ye yax basté, ~ ~ ~ rocidé

Fr.: ligne de champ magnétique gelée   

A → magnetic field line in a → fluid when the motion of the fluid carries the magnetic field along with it.

Frozen, p.p. of → freeze; → magnetic; → line.

magnetic field line
  خط ِ میدان ِ مغناتیسی   
xatt-e meydân-e meqnâtisi (#)

Fr.: ligne de champ magnétique   

An imaginary line used for representing the strength and direction of a magnetic field. Charged particles move freely along magnetic field lines, but are inhibited by the magnetic force from moving across field lines.

magnetic; → field; → line.

open magnetic field line
  خط ِ باز ِ میدان ِ مغناتیسی   
xatt-e bâz-e meydân-e meqnâtisi-ye

Fr.: ligne ouverte de champ magnétique   

In the context of solar physics, a → magnetic field line when it crosses the solar surface only once, i.e., when it goes from surface to infinity. This is the case at a sufficiently large scale in → coronal holes. This is mostly not the case in → active regions.

open; → magnetic; → field; → line.
