AB  - In the manufacture of magnetic iron oxide for recording tape, frequent tests must be made in order to maintain uniformity of the product. The simplest and quickest method has hitherto been the use of a B-H loop tracer, where the hysteresis loop is traced on the screen of a cathode-ray tube. This involves centering the pattern and reading the results on a previously calibrated screen and requires time and experience. This paper describes a method of testing magnetic materials, particularly magnetic iron oxide, where the most important properties, i.e. Bm, Br, Hm, and Hc are indicated directly on a meter with a calibrated scale.
