摘要：
The amplitude of magnetic permeability and electromagnetic losses are the basis of application of Fe-Ga alloy. Different magnetic hysteresis curves of Fe-Ga alloy are measured using AMH-1M-S dynamic testing system under different conditions, which are the same saturated magnetic field and the same maximum saturation flux density under different frequencies. The complex magnetic permeability, medium energy storage and magnetic losses are analyzed. Electromagnetic loss increases and energy storage of material reduces with increasing of frequency. Hysteresis loss increases linearly with increasing of frequency, the eddy current loss increases dramatically, and the residual loss increases rapidly. The experimental results of this paper can provide guidance for the design of high frequency Fe-Ga ultrasonic transducers.
