Morphology
moving-coil + galvanometer
The phrase literally describes a type of galvanometer: 'moving' + 'coil' indicates a coil that moves, and 'galvanometer' is an instrument for measuring current, so the overall meaning ('a galvanometer with a movable coil') is directly derivable from the parts. This is a literal, descriptive technical compound following standard English composition, so a B1 learner who knows the constituent words would grasp the meaning.
Etymology
Moving-coil galvanometer gets its name from a simple picture: a small coil of wire actually moves inside a magnet when electricity flows, and that movement turns a needle. So the device was used to 'measure' electric current.
