This paper studies the relationship between the B and H loci, and the power losses features of a soft magnetic composite in 3-D space when the B loci are controlled to be circles with increasing magnitudes and ellipses evolving from a straight line to a circle in three orthogonal planes. It is found that the B and H loci lie in the same magnetization plane, but the H loci and power losses strongly depend on the orientation, position, and process of magnetization. On the other hand, the H vector evolves into a unique locus, and the power loss approaches a unique value, respectively, when the B vector evolves into a round locus with the same magnitude from either a series of circles or ellipses.
