Morphology
magnetomotive + force + unit
The term is fully compositional: 'magnetomotive' specifies the kind of 'force' and 'unit' signals a measure, so a learner who knows the constituent meanings can infer it denotes a unit for magnetomotive force. The 'unit of X' construction is a standard, cross-linguistic nominal composition, so the meaning is predictable despite being technical.
Etymology
Magnetomotive force unit gives a simple picture: magnetomotive means a 'push' for magnets, force is a push, and a unit is a measure. Think of a pump pushing water through a pipe — this unit measures the 'push' that drives the magnetic field through a circuit, so it means 'a unit used to measure magnetomotive force'.
