ELECTRIC AND MAGNETIC POTENTIALS OF UNIFORMLY ACCELERATED CHARGE-DISTRIBUTIONS

Jefimenko gave recently [1] new expressions for the electric and magne tic potentials of uniformly moving, time-independent charge distributi ons. We discuss these potentials for uniformly accelerated distributio ns. As Jefimenko did, we implement two procedures either converting di rectly retarded into present position integrals or using relativistic transformations for a stationary charge in an instantaneous comoving i nertial frame (Frenet-Serret tetrad). We discuss why, at the differenc e of what happens for uniform motions [1], both procedures provide dif ferent expressions for potentials.
