Material electromagnetic fields and material forces

open access: yesArchive of Applied Mechanics, 2006
The paper investigates balance laws in an electromagnetic continuum, within the frame of configurational mechanics of materials. The author uses a non-conventional variational approach to introduce material momentum and material stress for electromagnetic continuum, and to derive a balance equation for the total material momentum of the system (matter +

Analysis of electromagnetic forces in high voltage superconducting fault current limiters with saturated core

open access: yesInternational Journal of Electrical Power and Energy Systems, 2012
This paper presents a three-dimensional numerical analysis of the electromagnetic forces within a high voltage superconducting Fault Current Limiter (FCL) with a saturated core under short-circuit conditions.

Proximal electromagnetic shear forces

Journal of Microscopy, 1999
We perform a simple model calculation to estimate the electromagnetically induced shear force caused by a current dissipation when a charged tip is moved parallel to a conducting material. For parameters typical in shear force imaging, the force is many orders of magnitude below reported values.

Limits on an Electromagnetic Fifth Force

Physical Review Letters, 1988
In analogy to the proposed gravitational "fifth" force, limits can be set on the range $\ensuremath{\lambda}$ and the strength $\ensuremath{\beta}$ of an electrical fifth force. Specifically we consider the potential $V=\frac{({e}^{2}}{r)}(1+{\ensuremath{\beta}e}^{\ensuremath{-}r\ensuremath{\lambda}})$ and show that there is a region near $\ensuremath{\
