Operation and Calibration of MRL Permeameter for Measurements of DC magnetic Properties of Materials under Stress

Abstract

This note describes the operation and calibration of experimental apparatus constructed at MRL for the measurement of the DC magnetic properties of steels. The instrument is capable of measuring normal induction curves and hysteresis loops at applied magnetic field strengths up to about 1 kA/m. A special feature is the ability to apply mechanical stress to the specimens before or during magnetic measurements. The stress and magnetic field are applied in the same direction in the specimen, and the magnetic induction is also measured in this direction. (js)
