Vector potential derivation from scalar potentials

THE AUTHOR recently published Tables of Green´s Functions¹ for the solution of partial differential equations in rectangular co-ordinates. The Green´s Functions, as given in those tables, include only scalar potentials. However, in dealing with the fields due to currents or permanent magnets, vector potentials usually are used. These vector potentials also can be derived from the Tables of Green´s Functions as is shown here.
