Morphology
The meaning is directly compositional: 'field' (a region of magnetic force) qualifies the noun 'magnet', so a 'field magnet' is naturally understood as a magnet that produces or relates to a magnetic field. Though technical, the compound follows regular English noun-noun composition and is cross-linguistically transparent, so a B1 learner who knows both words can infer the meaning.
Etymology
Field magnet literally names the part: the magnet that makes the field, the 'area of magnetism', inside a generator or electric motor. So it means the part that creates the magnetic effect the machine needs to work.
