Abstract
This instrument produces, automatically, a curve of torque versus angle of orientation for a thin iron or steel disk in a strong magnetic field. A resistance strain gauge converts the torque acting on the disk specimen to a small d.c. voltage, which is recorded on a ``strip‐chart'' recording potentiometer. The specimen is rotated in synchronism with the translation of the chart paper, both being driven by synchronous motors. A torque curve is completed in six minutes.
