The conventional field analysis methods neglect the phase relation between the magnetic flux density B and the magnetic field vector H under a rotating field. Magnetic properties have been measured as scalar relationships under an alternating magnetic field, and only the scalar values have been applied to analyze the two-dimensional magnetic field problems. In this paper, the B- and H-values have been measured as vector relationships under the influence of a rotating field, using the two-dimensional magnetic measurement apparatus. The magnetic properties are represented by a tensor expression as a function of magnetic reluctivities. This expression is then applied for the rotating field analysis.
