Morphology

field + coil

The compound directly combines 'field' (a magnetic/force region) with 'coil' (a wound wire), so its meaning — a coil associated with or producing a field — is transparently derived from the parts. This is a straightforward noun+noun technical compound following common compositional patterns found cross-linguistically, so a B1 learner who knows both constituents should be able to infer the meaning.

Etymology

Field coil gets its name from a simple picture: a coil, a ring of wire, wrapped around the machine's field, the magnet. Because the wrapped wire makes the 'magnetic field', the term means the wire coil placed around the magnet to produce that field.
