研究了交流信号电压、直流磁场和限流电阻对Fe_(73.5)Cu_1Nb_3si_(13.5)B_9非晶薄带磁感应效应和磁感应效应变化幅度的影响.结果表明,当信号为正弦交流电时,线圈感应电压也为同频率的正弦交流电压;当信号为矩形脉冲电压时,线圈感应电压则为同频率的尖脉冲电压.当信号为正弦交流电时,磁感应效应随着交流电压幅值的增大而增强,随着直流磁场强度和限流电阻的增大而减弱,磁感应效应变化幅度随着直流磁场强度和交流电压幅值的增大而增大,随着限流电阻的增大呈现出先增大后减小的趋势.

Influences of AC signal voltage, DC magnetic field and current limiting resistance on the magnetic induction effect and the amplitude of magnetic induction effect of Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9amorphous alloy ribbons were studied. The results showed that sine signal induces an alternating current of the same frequency, rectangle signal induces a sharp pulse voltage of the same frequency. When the signal is sine signal, the magnetic induction effect increases with the increasing of signal voltage amplitude, but decreases with the increasing of DC magnetic field and current limiting resistance. The amplitude of magnetic induction effect increases with the increasing of DC magnetic field and signal voltage amplitude, and increases first and then decreases with the increasing of current limiting resistance.
