Empirically correct electrodynamics

The electrodynamics that predicts all known relevant observations is based upon the force F=(qq ′R/R³) [1 − 2v·v′/c² + 3(v·R) (v′·R)/c²R² + (a — a′)·R/c²] on charge q at r with the absolute velocity v and acceleration a due to charge q′ at r′ with absolute velocity v′ and acceleration a′, where R=r − r′. This force yields Ampere’s original empirical law for the force between current elements, which predicts the many effects due to Ampere tension between colinear current elements. It yields Faraday induction as well as Müller’s localized unipolar induction. The force on an accelerating charge due to a stationary charge yields Lenz’s law for the induced back emf; and, when applied to gravitation, qq′ being replaced by — Gmm′, it yields the inertial force ma, confirming Mach’s priniciple. For charge velocities approaching the velocity of light c it predicts the results of the Kaufmann-Bucherer experiments and the Bertozzi experiment, assuming neomechanics, or mass change with velocity. It is readily written as a field theory. Introducing time retardation, it yields waves and radiation. It predicts the observed zero self-torque on the Pappas-Vaughan Z-shaped antenna. Energy is conserved. The Weber electrodynamic theory is shown to fail.
