Improved measurement of magnetic properties with 3D magnetic fluxes

Abstract

This paper, as a pioneering work, presents measurement techniques to characterize soft magnetic materials in threedimensional (3D) space. A novel 3D magnetic property tester using cubic sample has been constructed and calibrated. Some phenomena and problems of measurement caused by the imperfect winding and misalignment of coils are analyzed. The correction methods are proposed and employed. The new soft magnetic composite SOMALOY(TM) 500 is investigated.
