用示波器测量铁磁物质的磁滞回线

The loop-line measure of ferromagnet hystersis with oscillograph

论述了铁磁物质磁滞回线测量的基本原理.介绍了如何利用示波器观察和测量铁磁物质的磁滞回线、剩余磁感应强度和矫顽力.同时也详述了怎样描绘介质的基本磁化曲线和μ-H曲线.

It discusses the keystone of the loop - line measure of ferromagnet hystersis. It introduces that how to watch and measure the hysteresis loop - line, residual magnet and coercive force of ferromagnet through an oscillograph. At the same time it describes how to depict the basal magnetization curve and μ - H curve of ferromagnet.
