Title: Gravitational induction with Weber's force
Author: Tajmar, M.
Assis, A. K. T.
Abstract: According to Faraday's law of induction, when we change the current intensity in a primary electric circuit we can induce a current in a secondary circuit under appropriate conditions. An electric current means charges in motion. Microscopically we can express Faraday's law by saying that when we accelerate charges in the primary circuit, a force is exerted on charges of the secondary circuit, which can accelerate them. A similar effect also exists in gravity with accelerated masses, but of course with much less intensity. The phenomenon is called frame dragging and can be derived from general relativity theory. Here we present an alternative way to calculate such gravitational induction forces based on Weber's law that only involves simple mathematics and incorporates other fundamental concepts, such as Newton's third law, and Mach's principle as the origin of inertia. It therefore summarizes all low-velocity gravitationally relevant effects into a single equation.

metadata.dc.description.abstractalternative: Selon la loi d’induction de Faraday, en changeant l’intensité du courant dans un circuit primaire, nous pouvons induire un courant dans un circuit secondaire sous des conditions appropriées. Un courant électrique signifie des charges en mouvement. Microscopiquement, nous pouvons exprimer la loi de Faraday en disant que suite a` une accélération des charges dans le circuit primaire, s’exerce alors sur les charges du circuit secondaire une force capable de les accélérer. Un effet similaire existe aussi en gravité pour des masses accélérées, mais évidemment avec une intensité beaucoup plus faible. Le phénomène s’appelle l’effet Lense–Thirring et peut être obtenu de la relativité générale. Nous présentons ici une façon alternative de calculer de telles forces gravitationnelles induites basée sur la loi de Weber qui n’implique que des mathématiques simples et incorpore d’autres concepts fondamentaux comme la troisième loi de Newton et le principe de Mach comme origine de l’inertie. Nous résumons ainsi sous la forme d’une seule équation tous les effets de basse vitesse pertinents en gravitation.
