磁性材料の試料の開磁路減磁曲線を閉磁路減磁曲線にマッピングするための方法及び装置

Abstract

A method and apparatus for accurately mapping closed-circuit demagnetization curves to and from open-circuit demagnetization curves. The method utilizes open-circuit data from a pulsed field magnetometer (PFM) and computer modeling of both the PFM (open circuit) and permeability meter (closed circuit) devices. The method is more accurate than previous methods and can calculate the closed-circuit curve within the accuracy of both the PFM and permeability meter devices.
