Practical Hysteresigraph

Abstract
A relatively low-cost hysteresigraph has been developed which is suitable for both laboratory and industrial application. The instrument utilizes standard component parts and employs mutual inductance feedback to perform the necessary integrating operation. The instrument is reasonably insensitive to environment and permits direct recordings of hysteresis loops and magnetization curves to be made in less than one minute. Both theoretical and practical considerations of the instrument are presented.
