Abstract

PURPOSE: To obtain the intensity of magnetic field of the point when magnetic flux density becomes zero while subsequently increasing the maximum value of the strength of an excited magnetic field from zero and obtain the coercive force of a ferromagnetic material from the intensity of the magnetic field when the increment lowers below the predetermined value.
