Morphology

geomagnetic = magnetic (transparent) = geo + magnet + ic

The word is formed directly from the combining form geo- 'earth' plus magnetic, so the meaning is readily recoverable.

Etymology

The word geomagnetic starts with geo- meaning 'earth' and joins magnet meaning 'something that pulls metal'. So geomagnetic describes the Earth's magnetic field, the invisible force that makes our planet act like a giant magnet.
