SUMMARY
The discussion focuses on the long-term effects of elevated temperatures on magnetism, specifically regarding neodymium and samarium-cobalt magnets. Neodymium magnets lose strength permanently when exposed to temperatures exceeding 80°C, while samarium-cobalt magnets have a curie temperature of 800°C. After prolonged exposure to temperatures around 150°C, neodymium magnets do not regain their full strength upon returning to room temperature. The material composition significantly influences the stability and retention of magnetic properties over time.
