Q
Will the magnetic force disappear or weaken after using it for a long time?
Answer Question
A
The magnetic force will not disappear or weaken. All our magnetic products use neodymium iron boron magnets, which can maintain constant magnetism. It is the permanent magnet with the strongest magnetic force at room temperature so far, and the applicable ambient temperature is below 80 degrees.
