Measurement of stress based on the magnetoelastic interaction effect in ferromagnetic materials relies on a change in permeability due to stress. A method for quantitatively evaluating the stresspermeability relation by combining measured magnetic flux density near a specimen with nonlinear analysis of the magnetic field by a finite element method has recently been proposed. The purpose of the present study is to examine the effect of frequency used for magnetization on the stress-permeability relation. The flux density near the specimen under a condition of loading is measured for various frequencies used for magnetization in a low magnetic field. Coefficients in the equations of the stress-permeability relation are determined for various frequencies using the method for quantitatively evaluating the stress-permeability relation.
