nonmagnetic

The word is a modern scientific compound formed within English. The core element, 'magnetic,' traces back to the Greek 'magnētis lithos' (Magnesian stone), named for the region of Magnesia in Thessaly where lodestone was found. The suffix '-ic' was added via Latin to form adjectives. The prefix 'non-,' from Latin 'non' (not), is a productive negator in English, attached to adjectives to straightforwardly indicate the absence of the stated quality. Thus, 'nonmagnetic' logically constructs its meaning by directly negating the property of magnetism, describing materials like wood, plastic, or certain metals that are unaffected by magnetic fields.

Structure: non (not) + magnetic (having the properties of a magnet) - non: A prefix of Latin origin, meaning "not." It functions as a negative particle. - magnetic: An adjective of Greek origin (via Latin), from the root 'magnet-' referring to the lodestone or magnet, combined with the adjectival suffix '-ic' meaning "having the nature of." Its functional role is the core adjective to which the negation applies.
