geomagnetism singular

geomagnetisms plural

Morphology

geomagnetism = magnetism (semi-transparent) = geo + magnet + ism

The meaning is built transparently from geo- + magnetism, but the term is specialized scientific vocabulary and not fully predictable for an average learner.

Etymology

The word geomagnetism combines geo- 'earth', as in geography, and magnetism from magnet 'a thing that pulls iron'. So, geomagnetism means the Earth's magnetic field and the study of that field.
