demagnetization

This term is primarily used in technical, scientific, and industrial contexts. It describes a specific physical transition where a material loses its magnetic alignment, whether through an intentional process (like cleaning a tool) or an accidental failure (like overheating a component).

As an uncountable noun referring to a physical process or state, it does not typically take a plural form. It is often paired with adjectives describing the cause or speed of the process, such as "gradual," "complete," or "thermal."
