Morphology

magnetometer = meter (semi-transparent) = magneto + meter

A learner who knows 'meter' can infer a measuring instrument, but 'magneto-' is a technical combining form rather than an everyday English word.

Etymology

Magnetometer comes from Greek parts: magnet meaning 'lodestone' or 'magnet' and -meter meaning 'measure', the same -meter in thermometer. So a magnetometer is literally a 'magnet-measurer', which is why it is an instrument that measures the strength and direction of magnetic fields.
