Accurate magnetic properties measurement of the silicon steel plays an increasingly important role in electromagnetic devices design and optimization. However, with the 2D circular and elliptical magnetization, which usually exist in the corner joint of three-phase transformer and behind the teeth of AC rotating machines, there is lack of experimental data result in the difficulty of reaching high frequency induction at kilohertz range. In this paper, a novel two-dimensional (2-D) magnetic tester with ultra-thin silicon steel sheets is designed and analyzed. In order to improve the measurement precision, a combined B-H sensing structure is designed to avoid the local inhomogeneity of magnetic field distribution caused by drilling holes. Both the alternating and 2D rotating magnetic properties of non-oriented silicon steel M210-35A are systematically measured at a wide range of frequency and magnetic flux density.
