- To calculate the magnetic flux density, divide the total magnetic flux by the area through which it passes.
Examples
-

-
The magnetic flux density in the in the solenoid of the bar magnets is of course, infinite.
-

Morphology
This is a fully compositional noun phrase: 'density' (amount per unit volume/area) applies to 'magnetic flux' (the flow/amount of magnetic field), so a learner who knows the constituents can infer it means the amount of magnetic flux per unit area. The exact technical detail (perpendicular to the field, units in teslas) is specialist, but the core meaning is transparently derived from the parts and follows common cross-linguistic compounding patterns.
Etymology
Magnetic flux density comes from three parts: magnetic (about magnets), flux (a word for 'flow'), and density (how much is packed into an area). The image is of invisible magnetic lines flowing through a small area, so the phrase means how strong or 'dense' that magnetic flow is in one spot.
