pick The Lorenz gauge. In the Lorenz² gauge, we av V.A -Moto- = at (10.12)
It follows, then, that 1 qc V(r, t) = (10.46) 4лEо (rc - rv)' where v is the velocity of the charge at the retarded time, and is the vector from the retarded position to the field point r. Moreover, since the current density is pv (Eq. 5.26), the vector potential is p(r,tr)v(tr) но A(r, t) = Mo 4л form dt' { p(r, t,) dt', r 4л r or но qcv A(r, t) = = V(r,t). (10.47) 4π (rc - r. v) Equations 10.46 and 10.47 are the famous Liénard-Wiechert potentials for a moving point charge.15 = =
