Abstract

The force‒magnetic coupling effect of ferromagnetic materials is the result of the macroscopic influence of mechanical properties on magnetic properties under the joint action of a stress field and an applied magnetic field, which can essentially be attributed to the transformation of the microscopic structure of the magnetic domain leading to a change in material properties. Taking X80 pipeline steel as an example, the effect of stress on important magnetic parameters (maximum value of the applied magnetic field, value of coercivity, and value of residual magnetic induction) of ferromagnetic materials is investigated under different excitation intensities. The results indicate that the coercivity has the highest degree of sensitivity to stress. With full consideration of the effect of the leakage magnetic field of a semiclosed magnetic circuit, the coercivity is corrected by applying a magnetic conductive adhesive. At the same time, a combination of theoretical derivations and experiments is used to obtain the force‒magnetism coupling equation based on the principle of energy minimization, clarify the relationship model between coercivity and stress, and obtain the response law of coercivity to stress in the stages of elasticity and plastic deformation.
