摘要
We investigated magnetic properties of representative soft magnetic materials, then clarified that non-oriented iron-silicon steel maintains high permeability and shows the most stable temperature dependence of the properties in the temperature range from room temperature to 600 degrees C. The fundamental element for the development of a magnetic field sensor using non-oriented Fe-Si steel was composed and the changes in inductance of the element, are proportional to the permeability of the material, were evaluated by applying a magnetic field to the element. The inductance decreases with increasing the magnetic field almost linearly, indicating the possibility of a magnetic field sensor operating at high temperature up to 600 degrees C.
