The magnetic field and forces were calculated analytically and by FEM applying the Comsol Multiphysics package. Forces were calculated by the Maxwell stress tensor and by volume force density. Numerical results for real and ideal contours with the same linear dimensions are discussed. Comparison ...
Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that...

Curves, sometimes calledB-Hcurves, are used to describe magnetic materials. They are plotted withHas abscissa and with eitherMorBas ordinate. In the illustration,Bris the remanent induction (Br=Mr);Hcis the coercive force, or reverse field required to bring the inductionBback to zero; andMsis...
Their stability is solely determined by the radial distribution of the magnetic pitch in the neighborhood of the cylinder axis, and is independent of the presence of singular current density surface at the boundary of the field. 展开 关键词: magnetohydrodynamics force-free magnetic field stability ...

The force exerted on one electric current by the magnetic field of a second current has been calculated. This result is used to define the ampere in terms of the force between two parallel current-carrying conductors.doi:10.1016/B978-0-12-059860-1.50038-2George B. Arfken...
