On the basis of the solution of the Fourier transformed inhomogeneous wave equation expressed in terms of both the charge and current density source, two basic field equations are derived, from which the time‐dependent generalized Coulomb and Biot–Savart laws are readily obtained. For the specific case of an arbitrarily moving point charge, the use of the Fourier‐transform approach makes the derivation of two intermediate field equations, required to get the fields in both the Heaviside–Feynman and Liénard–Wiechert form, straightforward.
