Temperature significantly affects magnetization, with lower temperatures generally allowing magnetic domains to align more effectively due to reduced movement. Higher temperatures can lead to increased mobility of these domains, potentially making it easier to align them but also risking loss of magnetization. Cooling a magnet tends to enhance its strength by maintaining domain alignment. The discussion references Curie's law and the concept of Curie temperature, indicating that temperature plays a crucial role in magnetism. Overall, the relationship between temperature and magnetization is complex, with both heating and cooling influencing magnetic properties.
