You babbling, ignorant, stupid, ineducable, idiot, I reccommended you read
MODERN texts, that is texts written LONG after Heaviside died.

MODERN texts use the Biot-Savart law.
"1825 - Ampere publishes his collected results on magnetism. His
expression for the magnetic field produced by a small segment of current is
different from that which follows naturally from the Biot-Savart law by an
additive term which integrates to zero around closed circuit. It is
unfortunate that electrodynamics and relativity decide in favor of Biot and
Savart rather than for the much more sophisticated Ampere, whose memoir
contains both mathematical analysis and experimentation, artfully blended
together. In this memoir are given some special instances of the result we
now call Stokes theorem or as we usually write it. Maxwell describes this
work as ``one of the most brilliant achievements in science. The whole,
theory and experiment, seems as if it had leaped, full-grown and full-armed,
from the brain of the `Newton of electricity'. It is perfect in form and
unassailable in accuracy; and it is summed up in a formula from which all
the phenomena may be deduced, and which must always remain the cardinal
formula of electrodynamics.''

I am in the 21st century. It is the plazma time.

Why are you incapable of getting a current University level textbook, in
any
language, on electromagnetics and reading it?

Electromagnetics is a piece to teach (for children).

For adults are electrodynamics. In a current University level textbook are
many chapters.
The fields are only a math tool. Completly useless for electrons.
