Morphology
The meaning 'region around a magnet where magnetic force acts' is directly and transparently derived from combining 'magnetic' (possessing magnetism) with 'field' (an area or region where a force or effect is present). This is a regular compositional noun phrase common across languages and scientific usage, so a B1 learner who knows both constituents can readily infer the MWE meaning.
Etymology
Magnetic field is a way to picture a magnet and the 'space around it' where the magnet's pull works: magnetic points to the magnet and field suggests the area around it. So the phrase means the area where a magnet or an electric current can pull or push objects, which is why a compass needle lines up with the magnetic field.
