Apparatus for Continuous Recording of Coercive Force, Maximum Magnetization, and Remanent Magnetization of Ferromagnetic Materials

摘要

Continuous recording of 60 Hz B‐H loop parameters of ferromagnetic materials, as a function of temperature or time, is made possible by the apparatus described. Maximum magnetization is plotted simultaneously with either coercive force or remanent magnetization. The loop may also be displayed in the usual way using an oscilloscope, if desired. The main advantage of this system lies in the elimination of time‐consuming point‐by‐point data acquisition.
