The magnetic field associated with a magnet may be affected changes in temperature. Two parameters used to describe a magnet are the maximum temperature and the curie temperature.
The maximum temperature is the temperature in °C that a magnet can reach without losing any magnetic strength (fully recoverable).
The curie temperature is the temperature in °C above which a magnet becomes demagnetized. Once it is cooled it may have either have no or a very low magnetic strength.
A magnet subjected to a temperature between the maximum and curie temperature will maintain some but not all of its original magnetism (not fully recoverable).
