The rate at which energy or particles pass through an area

Morphology
The term is compositionally built from 'magnetic' (relating to magnetism) and 'flux' (flow or rate of passage), so the meaning 'amount of magnetic field passing through an area' is directly derivable from its parts. This follows a common noun–noun composition pattern and has clear equivalents in other languages, so a B1 learner who knows both constituents should understand it.
Etymology
Magnetic flux comes from a simple image: magnetic is about magnets and flux means 'flow', so it suggests magnetism moving through a surface. Imagine magnetic field lines like water flowing through a loop; the more 'flow' that goes through, the greater the magnetic flux, so the term means the total magnetic field passing through an area.
