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

Proximal electromagnetic shear forces
Journal of Microscopy, 1999We 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.

Reduction of Radial Electromagnetic Force Waves Based on PM Segmentation in SPMSMs
IEEE transactions on magnetics, 2020Electromagnetic vibration is excited by the electromagnetic force waves generated by the air-gap magnetic field acting on the machine core. In this article, a fast and accurate calculation method of radial electromagnetic force density of surface-mounted

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{\

IEEE transactions on industrial electronics (1982. Print)
In view of the shortcomings of the existing calculation methods of electromagnetic forces, this article proposes an analytical method (AM) combining the magnetomotive force permeance method and the improved subdomain method.

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.

Bridge measurement of electromagnetic forces
Electrical Engineering, 1935A simple impedance bridge may be used to measure the variation of inductance of a disconnecting switch of practical dimensions as the switch blade is displaced by slight amounts from the closed position. The electromagnetic force tending to open the switch blade, calculated from the observed variation of inductance, checks the theoretical value ...

IEEE transactions on industry applications, 2020
In inverter-fed electrical machines, the sideband current harmonics around the switching frequency introduce annoying vibration and noise that are difficult to predict by finite element method (FEM) due to their high frequency.
