Lastly , calculating the magnet performance using theoretical formulation , which expresses the relationship of the external magnetic field and remanence of the magnet , can tell the type of unknown magnet 另外，通过对磁体国防科学技术大学研究生院学位论文表面场的测量，并结合理论公式可以判断未知磁体类型。

Sem shows that the composite ferrite is like cotton and displays one by one , their diameters are about 50nm . vsm measurement in the strong magnetic field reveals that its coercive force and remanence are zero , that is , the product is supermagnetic one Sem表明复合型铁氧体呈“棉花状” ,颗粒排列紧凑,粒径在50nm左右;磁滞回线显示该铁氧体的矫顽力和剩磁均为零,证明其为超顺磁物质。

Being added an anti - phase compensating winding , this device , which is placed between high voltage line and first insulator , makes the synthesized magnetic field in magnetic core reach a dynamic balance , and thus solves the problems from remanence and assures the measurement accuracy 其漏电流传感器增加一个反相的补偿线圈，使得电流传感器磁芯内的合成磁场达到动态平衡，解决了由于剩磁而带来的问题，保证了测量精度。

The finer the grain is , the higher the magnetic properties are , such as the improvement of coercivity . according to the theory of remanence , the intensity of remanence is in direct proportion to the density of magnet and ms . the improvement of remanence resulted from the interaction of density of magnet and ms , but the ms took the more important role 究其原因：晶粒的细化可以提高磁体的矫顽力；而根据剩磁的理论公式，剩磁与磁体密度和饱和磁化强度成正比，剩磁的提高是磁体密度和饱和磁化强度的提高的综合效果，但其中饱和磁化强度的提高占主导地位。
