Electromagnetic forces on contacts
2008 43rd International Universities Power Engineering Conference, 2008These instructions give you basic electromagnetic force on an arcing contact is one of the principal factors in designing large-capacity and small-sized high current contact systems of circuit breakers, disconnectors or isolated switches. Butt contacts, such as those in vacuum interrupters, tulip contacts structured from a rod contact and fingers are ...

IEEE transactions on magnetics, 2020
For continuous or spiral windings which feature multiple continuously transposed conductors (CTC) wound in parallel, the transposition structure is commonly used to suppress circulation between conductors. This introduces a local asymmetry in transformer

Limits on an Electromagnetic Fifth Force
Physical Review Letters, 1988In 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, 2010Total 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.

An analysis of electromagnetic forces [PDF]
Electrical Engineering, 1945 Certain concepts of physics and electromagnetism conflict on several points, chiefly because of the latter's lack of general equations for the reaction of electrical particles. In this article the author introduces a few fundamental electrodynamic concepts and deduces from them some of the commonly used formulas for forces exerted on current-carrying ...
