What are the characteristics of the permeability of non ferromagnetic materials and ferromagnetic materials?
The difference is that ferromagnetism has the properties of spontaneous magnetization, so its muon value can be very large.
If you want to know very detailed information, you can search the Baidu library for "magnetic physics", and there will be a very detailed introduction.If you have any questions, please come to me at the forum. If you are busy, please accept the answer.
Non ferromagnetic material, if it is paramagnetic and diamagnetic material, one is greater than 1, one less than 1, but are similar to 1, ferromagnetic B-H nonlinear changes, permeability can be very large, the impact factor is also more.
