Morphology
The meaning is directly compositional: a 'line' located in or associated with a 'field', used to represent direction in a force field. This follows standard noun-noun formation and is cross-linguistically common (e.g., 'línea de campo'/'línea de fuerza'), so a B1 learner who knows both constituents can reasonably infer the MWE's meaning.
Etymology
Field line comes from the work of an early scientist, Michael Faraday, who used iron filings to show a magnetic field and drew a line through the pattern to show how the force moved. So today a field line is an imaginary line that shows the 'direction' and relative 'strength' of a force.
