Between statics and dynamics is kinetics. EM is the kinetics.

Should be kinematics (not kinetcs): "Branch of physics concerned with the
geometrically possible motion of a body or system of bodies, without
consideration of the forces involved. It describes the spatial position of
bodies or systems, their velocities, and their acceleration".

The kinematics describes motions without consideration what and why.

This could either get very confusing, or very revealing, not sure which
yet.

EM is the first step. No the next for the incompressible fluid. The electron
were discovered and the dynamics are done for them.

I found that no terms I knew fitted that well so I ended up using 'flux'
and
'stasis' NOT to be confused with motion and stillness. By which I mean
motion
and stillness are the phenomenon, but flux and stasis are what lies
beyond,
in a pattern of information for want of better expression. To illustrate,
a
tap turned to release a flow of water often shows a stationary pattern
while
water is obviously flowing. That pattern is a stasis, but the water is not
still. I don't know how useful this is when resolving a distinction
between
kinetics and dynamics, but it does look like we have to be careful about
how
we use these terms or we might not know which we're talking about, the
standing pattern, or a manifest stillness. If we can't be clear on it we
might as well be trying to pin down the 'evanescence of soul'. (Richard
Clark, that was a good one, it's right up there with the better phrases
from
Douglas Adams.)

For flows are also the flow kinematics and the flow dynamics.
"An accurate theory of electromagnetism, known as classical
electromagnetism, was developed by various physicists over the course of the
19th century, culminating in the work of James Clerk Maxwell, who unified
the preceding developments into a single theory and discovered the
electromagnetic nature of light. In classical electromagnetism, the
electromagnetic field obeys a set of equations known as Maxwell's equations,
and the electromagnetic force is given by the Lorentz force law. "

It seams that EM is the field kinematics.
