如题：在FEMM的材料库中，铁氧体的磁体是哪一个？

先谢了！

找下以前的贴子仔细看下.

就是没找到呀！

FEMM的材料在材料库中，其中PM Materials是永磁材料，又分为Alnico Magnets、NdFeB Magnets、Ceramic Magnets、SmCo Magnets四种，Alnico Magnets－铝镍钴磁铁；NdFeB Magnets－钕铁硼磁铁；Ceramic Magnets－铁氧体磁铁；SmCo Magnets－钐钴磁铁。

LINGYI兄已给你说的很清楚了,总可以找到了吧?在找不到的话,到狼音社区找下老贴了!

此主题相关图片如下：

此主题相关图片如下：

Y30相当于Ceramic5

Y30H-1相当于Ceramic8

Y20相当于Ceramic6

FEMM里只有Ceramic5和Ceramic8(BH图就是上图的两曲线),可以导入DAT文件(可以用文本编辑)

谢谢各位，讲的非常清楚！

ddddddddddddddddd

也可以自行输入数据

Ceramic8 应是Y35

没有类似Y35的.

有一张Y35的图可供参考,不知怎么上传?

正想了解这方面知识，TKS!

没有Y25的?俺们大部分铁氧体都是Y25的

lingyi兄的解释令我茅塞顿开，材料库中有导磁片的材料吗？
