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.

Electromagnetic force and torque on magnetic and negative-index scatterers [PDF]

open access: yesOptics Express, 2009
We derive the analytic expressions of the electromagnetic force and torque on a dipolar particle, with arbitrary dielectric permittivity and magnetic permeability. We then develop a general framework, based on the coupled dipóle method, for computing the

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{\

Computation of Local Electromagnetic Force

IEEE Transactions on Magnetics, 2010
Total electromagnetic force on a body can be predicted by replacing the magnetization and polarization with appropriate equivalent currents and charges. Still, the equivalence of total force does not imply that the integrated densities have physical meaning.
