One aspect of kinetic energy induction in charged elementary particles that attracted little attention during Walter Kaufmann's experiments in the first years of the 20th century, as he accelerated electron beams for the first time in history on curved trajectories in a bubble chamber by means of controling the energy levels that determined their velocity with a precisely calibrated E-field, and defined the curvature of their trajectories with an additional precisely calibrated B-field, a method proposed by Antoon Lorentz in the last decade of the 1800's and that was constantly used afterwards in cathode ray tube design, is the adiabatic nature of the energy induced in each electron of the beam.

The adiabatic nature of the kinetic energy induced by a non-permanant E-field such as the one used by Kaufmann was established only later by Aram D'Abro in the 1930's, as put in perspective in this paper published in 2022:

the amount of energy provided to each electron was calculated by means of the first term of the Lorentz force equation F=e(E+v×B), which is, in its expanded form, the Coulomb equation developed in 1782 by Coulomb during experiments involving point-like behaving charges, as put in perspective in the final paper of the electromagnetic mechanics project:

It turns out that the energy adiabatically induced in an electron in addition to the energy making up its rest mass is determined exclusively by the proximity of its charge with the charges of all other elementary charged particles according to the Coulomb law, as analyzed in this paper published in 2016 and republished as a book chapter in a specialized collection in 2021:

For readers unfamiliar with electromagnetic mechanics, the best way to insure clear understanding of each paper is to personally numerically resolve each equation along the way to confirm the validity of the numerical values provided, by means of a pocket scientific calculator.

This numerical validation process has been made easy by all equations involving only known physical constants and a single variable.
