  • Abstract
    In this study, we performed structural and mathematical modeling by using the method of space harmonics in accordance with magnetization conditions of the irreversible demagnetization. Based on the proposed modeling method, we calculated the equivalent magnetizing distribution and the back electric motive force (BEMF) under the demagnetization condition. Finally, we analyzed harmonic components for irreversible demagnetization through the fast Fourier transform (FFT) analysis of the BEMF.
