一、引言在材料直流磁性测量中,常用螺绕环和螺线管作磁化装置。它们产生的磁场,一般通过电流的测量进行计算,因而在磁化电路中总要串联一块多量限电流表。本文介绍的方法,是把这块电流表变成直接测取磁场的仪表,其优点是可以使测磁操作者对于磁场的调节心中有数、对磁场的测量快速可靠。这种仪表已在首都钢铁公司特钢公司冶金研究所和中国科学院物理研究所等单位使用多 I. Introduction In the material DC magnetic measurement, commonly used spiral ring and solenoid for magnetization device. The magnetic field that they produce, generally calculates through the electric current measurement, therefore must always be in the magnetization circuit in series with a large amount of limiting ammeter. This article describes the method is to change this ammeter to directly measure the magnetic field instruments, the advantage of enabling magnetic measurement operator for the adjustment of the magnetic field of mind, the measurement of the magnetic field fast and reliable. This instrument has been in the Capital Iron and Steel Company Special Steel Institute of Metallurgical and Chinese Academy of Sciences Institute of Physical and other units to use more
