摘要: 脉冲装置用于直流回复退磁时其电容电压值不易把握.利用试验法得到使铁磁体剩磁方向翻转的临界电压为最佳退磁电压,通过计算反向峰值磁场和脉冲电路参数得到电容电压公式,结合公式与实验规律能够快速获得退磁需要的电容电压.

Abstract: It is hard to select capacitance voltage of pulse device in static demagnetization. The critical voltage which turns the remanence direction is the best demagnetization voltage by experimental methods. The formula of capacitance voltage is given by solving the peak of magnetic field and pulse circuit parameters. The voltage can be selected quickly by combining formulas and experimentation conclusion.

Key words: electromagnetics, demagnetization, pulse circuit, capacitance voltage
