Powerful magnets also called ndfeb magnet.
This is a kind of artificial permanent magnets, is called powerful magnets because it is so far the strongest magnetic force of permanent magnet.
In some specific places with the powerful magnet to shenzhen.
General magnetic materials have a critical temperature Tc, shenzhen powerful magnets manufacturers more than the temperature will degaussing or demagnetization.
Dongguan powerful magnets and magnet at higher temperatures, their internal molecular thermal motion faster and faster.
When the temperature rises to a certain value, intense molecular thermal motion regularity of the direction of motion of the electron, the dongguan powerful magnet manufacturer magnet magnetic also disappeared.
