Combining Schwarz–Christoffel Mappings and Biot–Savart Law to Calculate the Clamping Plate Field in Large Salient Pole Synchronous Machines

IEEE transactions on magnetics, 2022
A new calculation approach for the contribution of the stator end winding field to the clamping plate field in large synchronous machines based on Biot–Savart (BS) law and Schwarz–Christoffel (SC) mappings is proposed in this article.

Magnetogram-matching Biot–Savart Law and Decomposition of Vector Magnetograms

Astrophysical Journal
We generalize a magnetogram-matching Biot–Savart law (BSl) from planar to spherical geometry. For a given coronal current density J, this law determines the magnetic field B˜ whose radial component vanishes at the surface.

All-dielectric magnetic dipole and Biot–Savart–Laplace law for displacement currents in the ring

Journal of Applied Physics
We have demonstrated that a dielectric plane ring with a high permittivity excited by an incident plane electromagnetic wave in the GHz frequency range is an almost ideal magnetic dipole for the basic resonance of incident radiation scattering.

A generalized Biot–Savart law and its application to the active scalar equations

Nonlinearity
In this paper, we study a generalized Biot–Savart law for suitable velocity that possibly diverges at infinity, and then show its application to the 2D general incompressible inviscid fluids.

Derivation of Biot-Savart Law and Lorenz Force and Unification of Gravitational and Electromagnetic Forces

Journal of Physics & Optics Sciences
We have derived the empirical Biot-Savart law and Lorenz force as well as the dynamic term of the gravitational force based on Ether Dynamics. The dynamic term of gravitation, together with the static term of Newton’s law of gravitation, allows ...

Transmission line sag and magnetic field analysis with sag parabolic equations and Biot-Savart law

International Journal of Electrical and Computer Engineering (IJECE)
This study presents a novel approach to enhance the precision of calculating sag and magnetic fields beneath overhead transmission lines. The Biot-Savart law is integrated with parabolic equations to assign multiple magnetic field sources to each ...

Fast and Accurate Evaluation of Biot-Savart Integrals over Spatial Curves in Periodic Domains

SIAM Journal on Scientific Computing
The Biot-Savart law is relevant in physical contexts including electromagnetism and fluid dynamics. In the latter case, when the rotation of a fluid is confined to a set of very thin vortex filaments, this law describes the velocity field induced by the ...
