Well, here I see we meet a serious problem, perhaps the barrier to
our efforts:

 1. There is no such thing as an *almost* inertial reference frame.

 2. Magnetism is *intrinsically* a relativistic effect. There is
    never a justification for ignoring relativity when treating
    questions of this sort. Purcell is a good source for teaching
    E&M with this fact held constantly in view, as is Feynman.
