WebAt high temperatures, any magnet will lose its magnetization rather quickly (in a matter of minutes, if the temperature is high). Answer 2: Magnets stay magnetized until something destabilizes them. The constant jostling of molecules (i.e. heat) slowly disorganizes the magnetic domains in a magnet, and this happens faster the hotter the magnet. WebBest. [deleted] • 11 yr. ago. Magnets lose an unsubstantial, negligible amount of "pull" over time. A typical permanent magnet will lose fractions of a percent of strength over many years.
