Ampère-Neumann Electrodynamics of Metals

Description

This book outlines the Newtonian electrodynamics of A. M. Ampère and F. A. Neumann which was further developed by Maxwell and Graneau. This topic is not covered in standard textbooks. The volume reviews a 170-year series of experiments which demonstrate the existence of longitudinal Ampere forces. Tension and compression predicted by Ampere force law is shown to be present in wire explosions, railgun recoil action, electromagnetic jets in liquid metals, and electric arc phenomena. The conventional Lorentz force law denies the existence of longitudinal forces acting along current streamlines. Experiments with an electrodynamic impulse pendulum have provided striking evidence of a failure of the relativistic energy law (E = mc²). The second editionof the book is highly recommended to physicists and engineers.

Graneau discusses Helmholtz E&M with k = 5, as cited by Assis 2014 p. 477.
