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.

Bridge measurement of electromagnetic forces

Electrical Engineering, 1935
A 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 ...

Electromagnetic Forces on a Superconductor

Physical Review, 1950
Measurements of the eddy current damping of the rotational oscillations of a tin sphere suspended in a magnetic field from a torsion fiber give the expected results as a function of the magnetic field and the conductivity as long as the tin is a normal conductor.

Electromagnetic Forces in Conductors

Journal of Applied Physics, 1967
Relaxation-averaging formulas are derived for magnetic-induction problems involving axially symmetric fields with sinusoidal or pulsed time dependence in media which may be linear or nonlinear, homogeneous or inhomogeneous. Solutions have been obtained from a high-speed digital computer for time-harmonic fields in linear, inhomogeneous media.

Electromagnetic forces on contacts

2008 43rd International Universities Power Engineering Conference, 2008
These 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 ...

The electromagnetic force

Abstract This chapter focuses on the electromagnetic force. It likens the Sun’s gravitational field to the electric charge of a static atomic nucleus emitting an electrical field with similar properties. In the equation of James Clark Maxwell, measurements of the strengths of electric and magnetic forces help determine magnetic ...

Electromagnetic force.

1998
Abstract It had been noticed by many different observers that in certain cases magnetism is produced or destroyed in needles by electric discharges through them or near them, and conjectures of various kinds had been made as to the relation between magnetism and electricity, but the laws of these phenomena, and the form of these ...

Electromagnetic Force Density in a Ferromagnetic Material

IEEE Transactions on Magnetics, 2004
Material derivatives for electromagnetic fields are presented. They are applied to determine the Maxwell stress tensor associated with different models of ferromagnetic materials. The accent is placed on the theoretical implications of the simplifying assumptions done in the different material models, with a thermodynamically consistent finite-element ...

Limits on new forces coexisting with electromagnetism

Physical Review D, 1994
We consider the limits arising from different electromagnetic systems on the existence of a possible new electromagnetic analogue of the fifth force. Although such a force may have no intrinsic connection to electromagnetism (or gravity), its effects could be manifested through various anomalies in electromagnetic systems, for appropriate values of the
