electric and magnetic fields of a moving point-like charge
By what, if any, methods other than by means of the Lienard-Wiechert
potentials can the electric and magnetic fields of a moving point-like charge be derived? Any references would be greatly appreciated. Armin

Any references would be greatly appreciated. Armin Try the Feynman-Heaviside formalism for the field of an accelerated point charge. You can find it in J D Jackson's 'Classical Electrodynamics' 3rd Ed.

Any references would be greatly appreciated. The Heaviside-Feynman equations give the fields directly (Heaviside did it first, but Feynman's later rediscovery seems to be better known). These can be found in Heaviside, Electromagnetic theory vol 3, and in the Feynman lectures. We used them in Pfeifer & Nieminen, Eur. J. Phys. 27, 521 (2006). But beware a typo in our equations - corrected in an erratum in 2007. The version on arxiv should be correct: http://arxiv.org/abs/physics/0602061 -- Timo Nieminen - Home page: http://www.physics.uq.edu.au/people/nieminen/ E-prints: http://eprint.uq.edu.au/view/person/...,_Timo_A..html Shrine to Spirits: http://www.users.bigpond.com/timo_nieminen/spirits.html
