In this paper presented a study of the remagnetization loss sensors to assess the level of fatigue damage accumulation under cyclic deformation and defect detection of continuity. In this paper presented the research results of the remagnetization loss sensors. In this paper obtained an expression of the phase sensitivity of the remagnetization loss sensors. In the work is revealed the dependence of the sensor signal phase from the weight gain of the metal due to the presence of the defect, the curve of the phase dependence from the magnetic resistance of the material during the handling of the phase voltage is represented, the dependence of the amplitude of the output signal from the air gap at a frequency of 25 Hz is represented. It has been shown that interfering factor is present in the form of an air gap between the poles of the sensor and the investigated metal in remagnetization loss sensors. The phase sensitivity of the sensor has a high value for small values of the magnetic resistance of the air gap.
