WebFree Divergence calculator - find the divergence of the given vector field step-by-step WebThe magnetic field has zero divergence, which means that. ∫ ∂ V B ⋅ d S = 0. We can interpret this by saying there's no net flow of magnetic field across any closed surface. This makes sense because magnetic field lines always come in complete loops, rather than starting or ending at a point.
