ferromagnetic
This term describes a specific class of materials, such as iron, cobalt, and nickel, that exhibit strong magnetic properties. It implies a high degree of permeability, meaning the material can concentrate magnetic flux and retain magnetization even after the external magnetic field is removed.
In technical discourse, it is used to distinguish these highly responsive materials from paramagnetic or diamagnetic substances, which have much weaker or repulsive reactions to magnets. It is almost exclusively used in scientific, engineering, and industrial contexts rather than in casual conversation.
Ý nghĩa
Having a strong attraction to magnets and capable of being magnetized permanently.
Ví dụ
