Morphology
The meaning 'an induction coil that generates high-voltage sparks' is directly derivable from combining 'spark' (a flash of electric discharge) with 'coil' (a wound wire component): it denotes a coil that produces sparks. This is a regular noun–noun compound with transparent composition, so a B1 learner who knows both words would readily infer the device meaning even if the technical context is unfamiliar.
Etymology
Spark coil comes from its simple job: a coil, a loop of wire, that makes a spark to start engines or help old radios work. That's why spark coil means a device that makes the electrical spark used to 'start engines'.
