Section … 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.

WebSep 12, 2024 · The electric flux density D = ϵ E, having units of C/m 2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential. It may appear that D is redundant information given E and ϵ, but this is true only in homogeneous media. The concept of electric flux density becomes important – and ...
