Mechanical Energy Conversion to Electromagnetic Energy for Magnetic Fluids: Theoretical Fundaments and Applications

Abstract

This article treats the static conversion of mechanical energy to electromagnetic energy, known as electromagnetic-acoustic, in magnetic fluids (E.M.A.) showing correlation to the “Theory of Sonics”, part of the domain named “Electro sonicity”. It retains the quality and is named magnetic fluid, a colloidal system formed by dispersing to monodomenic sizes, followed by the stabilization of a solid material with magnetic properties, in a liquid, usually with dielectrically properties. The electromagnetic–acoustic transformation [1] in a medium shows all the phenomenons linked to the kindling and recording of elastic oscillations by using the electromagnetic field or to the electromagnetic waves by using the mechanical oscillations. The original issues contained in this article are: (1) The highlighting of the physical and mathematical connection between the specific electrical formalism and the Theory of Sonics by introducing the sonic power in B8 (B18) formula. (2) The materialization of theoretical results on the conversion of mechanical energy into electromagnetic energy, as a vibration transducer whose originality is certified by the patent no 110872C1/1996 by title “Vibration transducer” [4].
