A. Hasenzagl et al., NOVEL 3-PHASE EXCITED SINGLE SHEET TESTER FOR ROTATIONAL MAGNETIZATION, Journal of magnetism and magnetic materials, 160, 1996, pp. 180-182
This paper describes a novel apparatus based on a 3-phase magnetic exc
itation which allows arbitrary multi-directional magnetization includi
ng dynamic rotational magnetization, II is based on a triple-yoke tech
nique, preferably used with a sample of hexagonal shape, Using a 3-pha
se power source, the most important magnetization patterns can be prod
uced even without dynamic control of the induction vector B due to the
fact that also practical 2-D patterns result from 3-phase excitation.
