Abstract
- For an infinitely long bar with rectangular cross section 2a×2b and constant susceptibility χ in a uniform transverse applied field H[sub a] along dimension a, the fluxmetric and magnetometric demagnetizing factors N[sub f,m] as functions of a/b and χ are accurately computed using a finite-elements method. By comparison of the computed results with exact analytical results for χ=-1,0,∞ and with a set of conjugate relations derived in this work, the elements distributions have been optimized to give a minimum discretization error. This error is further greatly reduced in the final results of N[sub f,m] by using an error correction approach previously proposed in a similar work for cylinders. © 2002 American Institute of Physics.
