Hi all,

I know the standard derivations for radiation of an accelerated point
charge: either by working out nonrelativistic dipole radiation or by
deriving Lienard-Wiechert potentials and then going to the limit v/c-0.

However, I've heard of some other nice way to look at this: by
considering a moving charge in external fields and using the equation of
motion (Laplace force). Somehow, one should be able to derive d/dt(W),
and the correct larmor expression.

Any ideas?
