Abstract
The electrodynamically expanded distinct element method (DEM) has been used to simulate isostatic, transverse and longitudinal magnetic field powder c ompaction. The particle shape (aspect ratio up to 2) increases the maximum gradient in magnetisation from 10% to 30%, the total magnetisation up to 10 %. An improvement up to 10% in magnetisation has been calculated for isosta tic compaction as compared to uniaxial compaction. (C) 1999 Elsevier Scienc e B.V. All rights reserved.
