The electromagnetic loss property was studied by the relative dielectric constant and relative magneticpermeability of the ferrites.
并测试样品的相对介电常数和相对磁导率,研究了它们的电磁损耗特性。

Before regular use of electro-magnet of the magnetic material Alnico, aluminum nickel and cobalt is very low coercivity, high magneticpermeability, however, it is easy to demagnetization.
以前电磁铁的磁性材料常使用的铝镍钴,铝镍钴的矫顽力很低,渗磁高,但是,很容易退磁。
