coercivity
In physics and materials science, this term describes a specific technical property of magnetic materials. It refers to the resistance of a ferromagnetic material to becoming demagnetized, which is a critical factor in determining the stability of permanent magnets.
In social and political contexts, the term shifts toward the capacity for compulsion. It describes the structural or systemic ability of an authority to enforce compliance through pressure or force. While related to "coercion," coercivity emphasizes the inherent power or potential to compel rather than the specific act of doing so.
Ý nghĩa
The intensity of the applied magnetic field required to reduce the magnetization of a ferromagnetic material to zero after the magnetization of saturation has been reached.
Ví dụ
