Abstract：The dynamic permeability and energy loss are the basis for the design and application of Fe-Ga alloy device. It is necessary to analyze the dynamic permeability and energy loss before studying the high frequency Fe-Ga alloysensor.In this paper, the dynamic permeability and loss model of ring-shaped Fe-Ga alloy is proposed, elastic permeability curve, viscous permeability curve and loss factor are measured using the AMH-1M-S dynamic magnetic propertytesting systemunder the different magnetic field frequency.Impedance and inductance values of ring-shaped Fe-Ga alloy are measured using the impedance analyzer.The elastic permeability and viscous permeability of the ring-shaped Fe-Ga alloy at different frequencies are calculated. The changes of the elastic permeability and the viscous permeability with the magnetic field frequency are analyzed.The results show that with the magnetic field frequency increasing, the elastic permeability firstly falls and then rises and viscous permeability constantly rises, the model calculation results are consistent with the experimental results.With the increasing of the magnetic field frequency, the loss factor increases first, then decreases and finally tends to be stable. The electromagnetic loss and media energy storage are both increasing withincreasing frequency.
