Does the temperature affect the magnetic force of the magnet?
It will be!
The temperature tolerance of magnets of various materials is different. Basically, the higher the temperature is, the lower the magnetic force will be. For example, the remanence temperature coefficient of sintered NdFeB is about – 0.12 ~ – 0.10% / ° C
If the working temperature of the magnet does not exceed the working temperature, when the temperature drops back, the magnetic force will recover. However, when the temperature exceeds the working temperature, permanent demagnetization will occur (if the structure of the magnet has not been damaged, the magnetic force can be recovered by magnetizing again).
The higher the temperature is, the faster the demagnetization speed will be. When the temperature is much higher than the working temperature, the magnetic force of the magnet may collapse instantly, making the magnetic force close to 0.
Each magnet can refer to product specifications, but also need to know more information, you can contact us by phone, thank you.
