Calculation of the Biot-Savart Law Magnetic Field Using Current Distributions Obtained from a Finite Element Analysis.

Abstract

Biot-Savart law magnetic field integration equations are derived for rod and plate elements, and for volume interface regions from an equation due to Wikswo. These equations have applications for problems where current distributions are present over extended volumes and are calculated on the basis of a finite element electric field analysis. The Biot-Savart field so calculated can be used in a further finite element analysis of the magnetic field about a body of high permeability located in the same region as the electric field.
