Causality in the Coulomb Gauge, O.L. Brill and B. Goodman, Am. J. Phys., Am. J. Phys. 35, 832-837 (1968)
A theoretical description and comparison of causal of causal relations in the the Lorentz and Coulomb gauges is presented with with special emphasis upon retardation and the Coulomb gauge. It is shown that the transverse character of the current density in the Coulomb gauge compensates for the apparent instantaneous Coulomb interaction, which appears as a formal consequence of the subsidiary condition imposed upon the vector and scalar potentials.
