1、 Do not place neodymium iron boron magnet products at excessively high temperatures, especially pay attention to their critical temperature. The critical temperature of ordinary neodymium iron boron magnets is usually around 80 degrees Celsius (176 degrees Fahrenheit). Adjusting the working environment temperature in a timely manner can minimize demagnetization phenomena.

2、 Starting from technology, we aim to improve the performance of products using neodymium iron boron magnets, enabling them to have a more temperature sensitive structure and less susceptible to environmental influences.

3、 You can also choose high coercivity materials with the same magnetic energy product. If that's not enough, you can only sacrifice a little magnetic energy product and find materials with higher coercivity that have a lower magnetic energy product. If that's not enough, you can choose to use samarium cobalt. As for reversible demagnetization, you can only choose samarium cobalt.

PS: Each material has its own unique characteristics, so choose the appropriate and economical one. When designing, it is important to consider everything carefully, otherwise it may cause losses!

Guess you also pay attention to: how to reduce or prevent thermal demagnetization and oxidation of neodymium iron boron, leading to a decrease in coercivity

Answer: This is a problem with thermal demagnetization, which is indeed difficult to control. Pay attention to temperature, time, and vacuum control during demagnetization.

How many frequencies will neodymium iron boron magnets demagnetize when they vibrate?

The magnetism of permanent magnets will not demagnetize due to frequency vibration, and high-speed motors will not demagnetize even when the speed reaches 60000 rpm.
