It is difficult for conventional one dimensional （1D） and 2D testing methods to analyze the magnetic properties of the magnetic materials comprehensively. A novel 3D magnetic properties testing method is studied in this paper, which can help to understand the magnetization process and analyze the core loss accurately. A 3D magnetic property tester was designed and 3D rotational magnetic properties measurement of the soft magnetic composite （SMC） materials under rotational excitations were carried out. Calibration and compensation of the novel B-tt sensing coils and accurate calculation of the B and H vectors were also analyzed in detail. According to the experimental results, 3D magnetic hysteresis properties and core loss features are analyzed and discued.
