The influence of neodymium iron boron magnets on clocks
NdFeB magnets have super strong magnetic force and are of great value in many fields. But improper use will often bring us unexpected troubles. For example, neodymium iron boron magnets can not be close to the clock.
What is the effect of neodymium iron boron magnets on clocks?
The neodymium iron boron magnet is close to the clock, it will stop the clock.
First of all, there is a component in the watch called the hairspring. The hairspring is most afraid of the magnetic field. When the watch is close to the neodymium iron boron magnet, the hairspring inside will be magnetized by the neodymium iron boron magnet.
When the balance spring is magnetized by neodymium iron boron, the balance springs in the watch will be glued, which can reflect the accuracy of the watch, and stop. So avoid direct contact with neodymium iron boron magnets.
It is best to keep a certain distance, the safe distance is 50CM. Of course, the larger the magnet, the stronger the magnetic force, and the safety distance should be appropriately increased.
Solution: After the watch hairspring is magnetized by the neodymium iron boron magnet, find the watch master to demagnetize it with a degaussing instrument, so that the watch can return to normal.
In addition, mobile phones, computers, bank cards and other items should not be close to NdFeB magnets. The strong magnetic field of NdFeB magnets will magnetize the parts in these items.
