WebBest. C34H32N4O4Fe • 10 mo. ago. Yes. Intuitively, the curl tells you how much a field, well, curls around a specific point (or an axis), while the divergence tells you the net flux of the field through a point (or a closed surface). Something that just circles around a point has zero flux through it. WebThe same equation written using this notation is. ⇀ ∇ × E = − 1 c∂B ∂t.
