Abstract: An improved three-dimensional (3-D) magnetic property measurement system, which can indirectly measure the magnetic field strength H vector in a cubic sample of soft magnetic composite (SMC) material by controlling the three components of the magnetic flux density B vectors, has been developed and calibrated. This paper especially describes the improved structure of the sample with H and B sensing coils, and deals with the magnetic compensation problem. The relationship between the B vector and H vector has been measured under alternating and rotating flux conditions by using the 3-D magnetic measuring system, and the core loss features have been analyzed when the B loci are controlled as circles with increasing magnitudes and ellipses evolving from a straight line to circle in three orthogonal planes.
