Morphology
The phrase is a straightforward adjective + noun composition: 'magnetic' (relating to Earth's magnetism) modifying 'equator' (an imaginary line), so its meaning as an equator defined by magnetic properties is directly inferable. Though the technical detail about 'no vertical dip' is specialized, the basic concept is compositional and cross-linguistically transparent, so a B1 learner who knows the constituents would grasp the general meaning.
Etymology
The term magnetic equator comes from the simple image of an invisible belt around the Earth where a compass needle shows 'no tilt'. Here magnetic points to Earth's magnetism and equator means the middle belt, so the name tells us the place where needles lie 'horizontal'.
