irrotational) vector field and a transverse (solenoidal, curling, rotational, non-diverging) vector field. Here, the terms “longitudinal” and “transverse” refer to the nature of the operators and not the vector fields. A purely “transverse” vector field does not necessarily have all of its vectors perpendicular to some reference vector.Solenoidal fields, such as the magnetic flux density B→ B →, are for similar reasons sometimes represented in terms of a vector potential A→ A →: B→ = ∇ × A→ (2.15.1) (2.15.1) B → = ∇ × A →. Thus, B→ B → automatically has no divergence.A vector field F in R3 is called irrotational if curlF = 0.

It means we can write any suitably well behaved vector field v as the sum of the gradient of a potential f and the curl of a vector potential A.
