Definition: at each point of a given space region, vector U, the rotation of which is the vector V of a given solenoidal field

V = rot U

Note 1 to entry: The given vector field is said to be derived from the vector potential.

Note 2 to entry: The vector potential is not unique since any irrotational field can be added to a given vector potential without changing its rotation. The vector potential is often chosen so that its divergence is zero.

Note 3 to entry: The vector potential is used, for example, to represent the magnetic vector potential (A), the rotation of which is the magnetic flux density (B).
