Abstract
An instrument developed to measure the magnetic properties of materials in a variety of forms by oscillographic techniques is described. Magnetic hysteresis loops can readily be obtained for specimens in rod, powder, tape, or wire form having cross‐sectional areas as small as 10−5 cm2 or as large as 0.3 cm2 (¼ in. rod). With slight modifications, the instrument can be adapted to magnetic measurements of materials as a function of frequency, temperature, tension, torsion, or pressure using the appropriate setup.
