Fe-based nanocrystalline core is widely used in pulse magnetic components because of its excellent soft magnetic performance. In order to design, or verify the performance of pulse magnetic components, it is necessary to test the pulse magnetization characteristics of magnetic cores according to the applications. A test stand based on LC ferromagnetic resonance and suitable circuit was built to determine the initial magnetization curves and hysteresis loops of Fe-based nanocrystalline cores with different remanences. For the comprehensive reflection of the pulse magnetization characteristics of Fe-based nanocrystalline cores, the trends of pulse permeability and loss density changing with magnetization rate were obtained. Besides, the mathematical relationship between pulse permeability, loss density and magnetization rate, magnetic induction increment was established by curve fitting. The pulse magnetization characteristics in this paper can provide the reference for designing and analyzing the working characteristic of pulse magnetic components under similar conditions.
