摘要：比磁化系数是物质重要的磁性参数，它对矿物的分选有重要的指导意义。通过查阅大量国内外资料，确定了比磁化系数测定仪磁极头的形状，通过ANSYS软件的模拟，对本研究所采用的磁极头文采用磁极头的优点确以肯定。将GPIB的接口转变为方便快捷的USB接口，使采集来的数据顺利快速的传输到计算机内。然后用Vb编制数据分析程序，其功能是将采集来的数据进行自动分析计算并输出目的数据。研究的比磁化系数测定仪，采用了新型磁极头，测定结果更加精准，且实现了数据的自动传输、自动分析计算，直接输出物质的比磁化系数和矫顽力。

Abstract：Specific susceptibility is the important parameters of magnetic material ,It has the important guiding significance for separation of minerals. This article consults a large number of domestic and foreign materials, had determined magnetic pole head shape of specific susceptibility tester. This article through the simulation of ANSYS software, affirmed the advantages of magnetic pole head that this article researched. In order to realize the automatic transmission of data. This article transforms the GPIB connection into the USB connection, witch causes collected data quick transmission in computer. Then establishes the data analysis procedure with VB, its function is that automated analysis computation the data collected and put data out. The specific susceptibility tester of this paper using the new pole, the determination results more accurate, and it realizes the data automatics transmission, automatic analysis, direct output of specific susceptibility and coercive force.
Key words：specific susceptibility；magnetic pole head；automation
