Loss of Magnetic Properties
If the temperature is increased to the Curie temperature, the magnet will permanently lose its magnetism. The atoms then vibrate so intensely that there is no global orientation anymore, as a result of which the magnet demagnetises. The same can happen due to mechanical shock, oxidation, or exposure to very strong external fields. This loss cannot be repaired; thus, it is irreversible.
Conversely, we have reversible loss, which is the temporary loss of magnetism, e.g., due to change of temperature. This loss can be reversed by cooling and/or remagnetisation.
