Design and Performance Analysis of Permanent Magnet Claw Pole Machine with Hybrid Cores

open access: yesCES Transactions on Electrical Machines and Systems, 2023
Permanent magnet claw pole machine (PMCPM) is a special kind of transverse flux permanent magnet machine. Compared with other electrical machines, it has the advantages of high torque density and high efficiency for high speed operation. However, because

Electromagnetic field with constraints and Papapetrou equation

open access: yes, 2006
It is shown that geometric optical description of electromagnetic wave with account of its polarization in curved space-time can be obtained straightforwardly from the classical variational principle for electromagnetic field.

The scalar complex potential and the Aharonov-Bohm effect

open access: yes, 2010
The Aharonov-Bohm effect is traditionally attributed to the effect of the electromagnetic 4-potential $A$, even in regions where both the electric field $\mathbf{E}$ and the magnetic field $\mathbf{B}$ are zero. The AB effect reveals that multiple-valued

Covariant Irreducible Parametrization of Electromagnetic Fields in Arbitrary Spacetime

open access: yes, 2006
We present a new unified covariant description of electromagnetic field properties for an arbitrary space-time. We derive a complete set of irreducible components describing a six-dimensional electromagnetic field from the Maxwell and metric tensors ...

Electromagnetic field effects on $\Upsilon$-meson dissociation in PbPb collisions at LHC energies

open access: yes, 2017
We investigate the effect of the electromagnetic field generated in relativistic heavy-ion collisions on the dissociation of $\Upsilon$ mesons. The electromagnetic field is calculated using a simple model which characterizes the emerging quark-gluon ...

On the existence of the field line solutions of the Einstein-Maxwell equations

open access: yes, 2017
The main result of this paper is the proof that there are local electric and magnetic field configurations expressed in terms of field lines on an arbitrary hyperbolic manifold. This electromagnetic field is described by (dual) solutions of the Maxwell's
