I looked at this ages ago - the change in momentum represented by such
a force happens, not via change of velocity (speed or direction) but
by change of mass of the electron. Formally one can think of a
(reducible) EM field living in the even subalgebra of the Dirac
algebra, with an additional scalar (and possibly pseudoscalar) field.
Such a field leads to a force law
F = pE +[/itex] JxB + NJ
where N is the scalar field and (p,J) is the charge-current density.
If we assume a convected current J = pV we get your term. Putting this
equal to the dotted momentum, and writing J in terms of electrons and
\delta functions, you'll see that N acts on the mass of the electron.
I seem to recall a Canadian guy named Watson who did some work in this
direction. No idea what journal.
Note that in one interpretation, the new force distinguishes between
matter and antimatter - for the latter
F = pE + JxB [itex]- NJ
It occured to me that the action on the mass may be one way of
thinking about the relationship of the muon to the electron.

Let me see if I understand you correctly. The change in momentum is
dp/dt = d(mv)/dt= mdv/dt + vdm/dt= ma + vdm/dt
Since m = Energy/c^2, we can write the last term as
vdm/dt = (v/c^2)d(Energy)/dt
The time component of the force, classically, is
d(Energy)/dt = qv.E
so vdm/dt = (1/c^2)qv(v.E) and
dp/dt = ma + (1/c^2)qv(v.E)
Thus the classical equation of motion can be written
dp/dt = ma + (1/c^2)qv(v.E) = qE + qvxB
or
ma = qE + qvxB - (1/c^2)qv(v.E)
I assume you are referring, in your comment, to the last term
(1/c^2)qv(v.E), where v is the velocity of the test particle q. This is
_not_ the same as my term (1/c^2)qv(v'.E), where v is the velocity of
the test particle q, and v' is the velocity of the _source_ q' of E (I'd
like to point out that my term (1/c^2)qv(v'.E) is from actreact.pdf not
biotcomp.pdf).
If my assumption is incorrect, please let me know.

Are you saying that N = (1/c^2)v'.E? If so, how is N derived?

Essentially dm Am is promoted to a dynamical field alongside dmAn -
dnAm. Maxwell's eqns are now
div E - dN/dt = \rho
curl B - dE/dt + grad N = Jdiv B =
curl E + dB/dt =
or in 4-d notation
(Fmn + gmn N),n = Jm
In terms of potentials
E = -grad \phi - dA/dt[/itex]
B = curl A
N = -div A - d \phi/dt
The current J is no longer directly conserved:
div J + d \rho/dt = (del^2 - dt^2) N
Note that we still have the usual equation for A in terms of the
current:
(del^2 - dt^2) Am = Jm
so the new field measures the extent to which charge is not conserved.
Now the Lorentz 4-force is
(Fmn + gmn N) Jn
and so
Fk = pE + JxB + NJF4 = J.E + Np
One can restore the conservation of charge by introducing a second
current
Kn = (Fmn + gmn N),m
and so (Jm + Km) is conserved. One then ends up with a theory with two
currents whose sum alone is conserved, suggesting that one is matter
and the other antimatter and that they can mutually annihilate - but
is it a hollow theory because the field is reducible to the bivector
F, which has its source in the conserved current, and the scalar N,
which has its source in the rate of creation-annihilation of matter
and antimatter.
The force on matter is
d/dtau (M Vm) = (Fmn + gmn N) Jn
= dM/dtau Vm + M dVm/dtau
where M is the mass density.
Assuming that Jn is convected p Vn and so proportional to the momentum
density,
dM/dtau Vm + M dVm/dtau = Fmn p [itex]Vn + p Vm N
Contracting with Vm
dM/dtau = p N
and for antimatter,
dM/dtau = -p N
In short, the idea of div A being a dynamical field is partially
seaworthy, but runs aground on the shore of reducibility. It actually
amounts to a grafting of the usual theory of the bivector field with
that of a new scalar field whose source is the rate of
creation-annihilation of matter-antimatter. The idea can be rescued by
enlarging the transformation group so that F and N are themselves
parts of an irreducible whole, and N is only a 4-scalar from the
perspective of the restricted set of transformations that correpsond
to the Lorentz group.
(Apologies for any sign errors in the above :)
