Solution to problem 2

... Notice that the potentials are not uniquely determined; one may always perform a gauge transformation, φ → φ + ∂t Γ and A → A − ∇Γ, and find the same electric and magnetic fields. Four-potential. To write it in the special relativistic language, one introduces the four-potential Aµ = (φ, A). Its gau ...

Larmor`s Formula

... “Larmor’s formula”, using a classical treatment due to J.J. Thomson and revived by Malcolm Longair. The ab initio derivation using Maxwell’s equations gives the same result. We start by taking a stationary charge at rest at time t = 0. The field lines from that charge have the simple configuration s ...

... also a function or r) – see previous handout for more discussion of opacity. These 4 equations have 7 unknowns (at a given r): P , Mr , Lr , T , ρ, ǫ, κ. So in general we require expressions for P , κ, and ǫ in terms of ρ, T , and the compositions. These can be complicated, but for example if we ass ...
