Control of a sedimenting elliptical particle by electromagnetic forces
, 2021 In this paper, the effectiveness of electromagnetic forces on controlling the motion of a sedimenting elliptical particle is investigated using the immersed interface-lattice Boltzmann method (II-LBM) in which a signed distance function is adopted to ...

Force Calculation in Electromagnetic Devices [PDF]
, 1988 In this paper the authors show how the Maxwell stress tensor can be used, in practice, in order to determine local magnetic forces distribution in an electromagnetic system. An experimental set-up has been designed in view of comparing the theoretical results with the measurements.

THE LAW OF ELECTROMAGNETIC FORCE
Electrical Engineering & Electromechanics, 2014 Calculation peculiarities for Lorentz force, Ampere force, interaction of parallel electric currents, and the moment of electrical machines are analyzed. They have exceptions on application, and they are the rules which result from the law of electromagnetic force as coordinate derivative of the operating magnetic flow.

Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]
, 2005 For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.

Electromagnetic forces in negatively refracting photonic crystals
, 2017 Electromagnetic (EM) waves exert forces on objects. The nonconservative part of these forces is determined by the gradient of phase (wavevector) of EM field. Through special structures, manipulation of the direction of these forces becomes possible. Here
