Interaction Between Magnetic and Stress Field in Ferromagnetic Core of Magnetoelastic Pressure Force Sensor

摘要

The paper deals with approximate solution of interaction between magnetic and stress fields in the ferromagnetic core of magnetoelastic sensor. The application of mechanical compressive force to the sensor results in mechanical stress within the core body and produces the variation of material permeability due to mechanical stress. The deformation of the magnetic field distribution and magnetic flux density caused by mechanical stress is given in graphical form.
