| + | <blockquote>Divergence (div) is “flux density”—the amount of [[basic_tools:vector_calculus:flux|flux]] entering or leaving a point. Think of it as the rate of flux expansion (positive divergence) or flux contraction (negative divergence). If you measure flux in bananas (and c’mon, who doesn’t?), a positive divergence means your location is a source of bananas. You’ve hit the Donkey Kong jackpot. | ||

| - | --> Example1# | + | The divergence is a crucial tool, for example, in [[models:classical_electrodynamics|electrodynamics]]. This can be seen immediately because the fundamental equations of electrodynamics (called [[equations:maxwell_equations|Maxwell equations]]) contain the divergence of the electric and magnetic fields. |
