Can rare earth Nd-Fe-B permanent magnets withstand minus 50 ℃ below zero?

Many of us know that NdFeB magnets have a strong magnetic force, but the disadvantage is that they are not resistant to high temperature (the temperature tolerance limit is 230 ℃, and the temperature tolerance of ordinary materials is 80 ℃). Since NdFeB magnets can not withstand high temperature, can they withstand low temperature? How many degrees can it withstand low temperature? Will demagnetization occur when used in low temperature environment? Today’s article unified answer, satisfy your curiosity.

1584929604815603 - Can rare earth Nd-Fe-B permanent magnets withstand minus 50 ℃ below zero?

Can rare earth neodymium magnets withstand low temperature?
The answer is yes.
Can rare earth Nd-Fe-B permanent magnets withstand minus 50 ℃ below zero?
Yes, even if the temperature is at – 60 ℃, it will not have any effect on it. On the contrary, low temperature will enhance its paramagnetism and enhance the stability of its electronic arrangement.
Nd-Fe-B strong magnet can withstand low temperature several degrees?
Magnets like the cold, and neodymium magnets will continue to function at operating temperatures as low as – 130 ° C. It is said that at this point, the magnetic direction has shifted, thus reducing the performance by about 15%. It should be noted that if the magnets are moved from very cold temperature to very hot temperature, this kind of thermal shock may cause them to rupture.
