Therefore, the observed non-zero linking is a ... WebHere are two simple but useful facts about divergence and curl. Theorem 16.5.1 ∇ ⋅ (∇ × F) = 0 . In words, this says that the divergence of the curl is zero. Theorem 16.5.2 ∇ × (∇f) = 0 . That is, the curl of a gradient is the zero vector. Recalling that gradients are conservative vector fields, this says that the curl of a ...
