7.6 Solutions for moving point charge 7.6.1 Problem description point charge charge trajectory (parameterized by time t) Setting: Non-trivial calculation! Here: calculate follows along similar lines 7.6.2 Lienard-Wiechert potentials Note: it is not trivial to execute -function! - dependence Define: relative position at retarded time (field evaluation point, particle) Lec 25 - 11.

Unformatted text preview: 1) at retarded time-> see Griffith 10.3.1) 2) with extra factor (geometric interpretation Lecture Notes Page 2 7.6.3 Electromagnetic Fields (suppress argument) … lengthy calculation=> see Griffith! Discussion: 1) 2) Radiation: comes from second term in only no radiation only accelerated charges create radiation need to be able to solve for retarded time ! 3) for any specific path taken by charge: Lecture Notes Page 3...
