摘　　要：磁材料已广泛应用于电子设备中,越来越贴近人们的日常生活需要。根据铁磁材料的磁特性的实验原理,用霍尔传感器进行了直流磁特性测量实验,测试并对比分析了铬、黑锌、白锌、彩锌四种材料的磁化曲线和磁滞回线,进而得到磁性能的差异性,同时,对比分析了四种材料的剩磁、矫顽力、最大磁感应强度等参数,得到磁化强度突变的原因。这与理论分析相一致。通过对比分析磁化曲线、磁滞回线及磁性参数等,这有利于学生加深理解磁性材料的磁性能,同时,能够更好地提高学生的综合实验能力。Magnetic materials have been widely used in electronic equipment and are the closer to people's daily needs.According to DC magnetic characteristic measurement experiment with Hall sensor,the magnetization curves and hysteresis loops of four materials was tested and analyzed the parameters such as remanence,coercive force and maximum magnetic induction intensity,and then got the difference of the magnetic properties and the reasons for the sudden change of magnetization,such as chromium,black zinc,white zinc and color zinc.Finally,the results are consistent with the theoretical analysis.So it is helpful for students to deepen their understanding of the magnetic properties and improve their experimental comprehensive ability.
