剩磁 Remanence(重定向自Remanent magnetization)
![]() 剩磁(Remanence)符号为Br,是指磁体经磁化至饱和以后,撤去外磁场,在原来外磁场方向上仍能保持一定的磁化强度。剩磁的极限值为饱和磁化强度。永磁材料的剩磁主要受材料中各个晶粒取向和磁畴结构的影响。 用剩磁可以量测磁化的程度,当磁铁被磁化后,就有剩磁。磁保存设备就是利用剩磁来记录数据,在古地磁学研究地球磁场时,剩磁也可以提供许多的信息。 在磁铁以外的工程应用时,剩磁也会称为剩余磁化(residual magnetization)。像变压器、马达及发电机及电磁钢一般不希望有太大的剩磁,因为剩磁会带来不想要的结果,例如电磁铁若有剩磁,在线圈不导通时仍然会有磁性。剩磁可以利用退磁的方式去除。

Remanence 剩磁(重定向自Remanent magnetization)
![]() Remanence or remanent magnetization or residual magnetism is the magnetization left behind in a ferromagnetic material (such as iron) after an external magnetic field is removed. It is also the measure of that magnetization. Colloquially, when a magnet is "magnetized" it has remanence. The remanence of magnetic materials provides the magnetic memory in magnetic storage devices, and is used as a source of information on the past Earth's magnetic field in paleomagnetism. |
