Automated Measurement System for Hysteresis Lines and Magnetic Parameters of Magnetic Materials

Abstract

As an indispensable part of materials in both production and life, magnetic materials are crucial to scientific research and economic development. The magnetic properties of magnetic materials are the basis for measuring the quality of materials, and the material magnetization curve and hysteresis loop are the effective characterizations of the magnetic properties of materials. In this paper, we design a new fully automatic and high precision hysteresis measurement system based on the high precision NI PXI-4461 data acquisition card according to the requirements of the national standard GB/T 3658–2008, and realize the automatic measurement and analysis of hysteresis and magnetic parameters.
