Morphology

magnetograph = magnet (semi-transparent) = magnet + graph

The word is recognizably built from magnet + graph, but the specific scientific meaning of a magnetic-recording instrument is specialized rather than fully predictable.

Etymology

The word magnetograph is made from magnet (a metal object that 'attracts' iron) and -graph (which means 'to write', like in photograph). So a magnetograph is a device that 'writes down' or records magnetic changes, which is why scientists use it to measure the Earth's or the Sun's magnetic field.
