Surface Forms
Morphology
The meaning is directly and compositionally derived from 'magnetic' (by magnets) + 'levitation' (suspension/lifting), i.e., lifting/suspending by magnetic forces. This construction is transparent and cross-linguistically comparable, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
Magnetic levitation paints a clear picture: strong magnetic forces lift something so it seems to levitate, or 'float', above a track. Because the object does not touch the surface, it can move very smoothly and quickly, so the phrase means using magnets to lift and move something 'without contact'.
